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.

How can we change an equation to another equation that is equivalent to it? Multiplying fractions is fairly straightforward.

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.

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.

For example, in the fraction of 3 8 , the numerator is 3, and the denominator is 8. Upon completing this section you should be able to: Classify an equation as conditional or an identity. Multiplying all of the denominators ensures that the new denominator is certain to be a multiple of each individual denominator. Get step-by-step results for proving mathematical statements. It is best to use the least of such numbers, which you will recall is the least common multiple. Now we must eliminate 2x on the right side by subtracting 2x from both sides. In this chapter we will study some techniques for solving equations having one variable. Since the answer is right, Algebra Calculator shows a green equals sign. Always Check! Remember to always check your solution. To eliminate the fraction we need to multiply by a number that is divisible by the denominator. Once again, we will rely on previous knowledge.

It does, however, require the understanding that each decimal place to the right of the decimal point represents a power of 10; the first decimal place being 10 1 , the second 10 2 , the third 10 3 , and so on. Refer to the addition section as well as the equations below for clarification. I thus need to subtract Ax from both sides. So we proceed as follows:. The answer to the second question involves the techniques for solving equations that will be discussed in the next few sections. First subtract 6 from both sides. Example 5. Using the least common multiple can be more efficient and is more likely to result in a fraction in simplified form. We should think in this manner:. You may want to leave your answer as an improper fraction instead of a mixed number. To check an answer to a system of equations containing x and y, enter the two equations separated by a semicolon, followed by the sign and an ordered pair containing your x-value and y-value. A solution or root of an equation is the value of the variable or variables that make the equation a true statement.
