The solution of equations is the central theme of algebra. In this chapter we will study some techniques for solving equations having one variable. To accomplish this we will use the skills learned while manipulating the numbers and symbols of algebra as well as the operations on whole numbers, decimals, and fractions that you learned in arithmetics. Upon completing this section you should be able to: Classify an equation as conditional or an identity.

MathPapa Toggle navigation. This is a tutorial on how to use the Algebra Calculator , a step-by-step calculator for algebra. Solving Equations First go to the Algebra Calculator main page. In the Calculator's text box, you can enter a math problem that you want to calculate. Examples To see more examples of problems that Algebra Calculator understands, visit the Examples page. Feel free to try them now. To graph a point, enter an ordered pair with the x-coordinate and y-coordinate separated by a comma, e. To graph two objects, simply place a semicolon between the two commands, e. Polynomials Algebra Calculator can simplify polynomials, but it only supports polynomials containing the variable x. Evaluating Expressions Algebra Calculator can evaluate expressions that contain the variable x. To evaluate an expression containing x, enter the expression you want to evaluate, followed by the sign and the value you want to plug in for x. Algebra Calculator can also evaluate expressions that contain variables x and y. To evaluate an expression containing x and y, enter the expression you want to evaluate, followed by the sign and an ordered pair containing your x-value and y-value.

Multiplying each side of the equation by 15, we obtain Why do we multiply both sides by 15? Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator.

Below are multiple fraction calculators capable of addition, subtraction, multiplication, division, simplification, and conversion between fractions and decimals. Fields above the solid black line represent the numerator, while fields below represent the denominator. In mathematics, a fraction is a number that represents a part of a whole. It consists of a numerator and a denominator. The numerator represents the number of equal parts of a whole, while the denominator is the total number of parts that make up said whole.

See how to show your work for arithmetic problems. That is, in the expression 5x the coefficient is 5. If the fraction were instead 5 , the decimal would then be 0. Polynomials Algebra Calculator can simplify polynomials, but it only supports polynomials containing the variable x. See if you obtain the same solution by multiplying each side of the original equation by In this chapter we will study some techniques for solving equations having one variable. Here is an example evaluating the expression xy at the point 3,4 : xy 3,4. In both cases, fractions are presented in their lowest forms by dividing both numerator and denominator by their greatest common factor. See the steps for analyzing data and applying statistical methods. Now we must use the division rule. Partial Fractions. Please enable JavaScript.

The equation solver allows to solve equations with an unknown with calculation steps : linear equation, quadratic equation, logarithmic equation, differential equation. Equation calculator An equation is an algebraic equality involving one or more unknowns. Solving an equation is the same as determining that unknown or unknowns.

The answer to the second question involves the techniques for solving equations that will be discussed in the next few sections. The second step toward an orderly procedure for solving equations will be discussed in this section. A solution or root of an equation is the value of the variable that makes the equation a true statement. In fact, it is possible that a single problem could involve all the rules There is no mandatory process for solving equations involving more than one rule, but experience has shown that the following order gives a smoother, more mistake-free procedure. Many of the exercises in previous sections have required the use of more than one rule in the solution process. An equation is a statement in symbols that two number expressions are equal. The solution of equations is the central theme of algebra. Algebra Calculator can also evaluate expressions that contain variables x and y. First subtract 6 from both sides. Example 9 What number x has the same ratio to 3 as 6 has to 9? Fields above the solid black line represent the numerator, while fields below represent the denominator. Note that in the example just using the addition rule does not solve the problem.
