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 x 1 6 x 3 2 1 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.

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. For example, in the fraction of 3 8 , the numerator is 3, and the denominator is 8. A more illustrative example could involve a pie with 8 slices. If a person were to eat 3 slices, the remaining fraction of the pie would therefore be 5 8 as shown in the image to the right. Note that the denominator of a fraction cannot be 0, as it would make the fraction undefined. Fractions can undergo many different operations, some of which are mentioned below. Unlike adding and subtracting integers such as 2 and 8, fractions require a common denominator to undergo these operations. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. The numerators also need to be multiplied by the appropriate factors to preserve the value of the fraction as a whole.

Notice how new ideas in algebra build on previous knowledge. In fact, it is possible that a single problem could involve all the rules. This would make the fractionwhich simplifies tosince the greatest common factor between the numerator and denominator is 2.

Upon completing this section you should be able to: Use the division rule to solve equations. If there are 24 men in the class, how many women are in the class? If the margin M was one-fifth of the cost C , find the cost of the article. Always check in the original equation. 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. Help Tutorial. Learn how to manipulate and solve expressions with variables step by step. We now come to the last of the four basic operations in developing our procedure for solving equations. Example 6 Solution Here our task is the same but a little more complex. Solution To solve for x we first write the proportion: Next we multipy each side of the equation by 9. An identity is true for all values of the literal and arithmetical numbers in it.

The equation solver allows to solve equations with an unknown with calculation steps : linear equation, quadratic equation, logarithmic equation, differential equation.

Find the radius of a circle if the circumference is measured to be If the fraction were instead 5 , the decimal would then be 0. It consists of a numerator and a denominator. We will therefore multiply by The solution or root is said to satisfy the equation. In fact, it is possible that a single problem could involve all the rules. Errors are sometimes made in very simple situations. An identity is true for all values of the literal and arithmetic numbers in it. Solve proportions. One method for finding a common denominator involves multiplying the numerators and denominators of all of the fractions involved by the product of the denominators of each fraction. If we choose to first add 2x to both sides, we obtain We now add 2 to both sides. Could we first add 2 to both sides? In mathematics, a fraction is a number that represents a part of a whole.
