# Linear Equations with Fractions – Examples and Practice Problems

Linear equations are equations that only have variables with a power of 1. To solve linear equation problems with fractions, we have to multiply the entire equation by the least common multiple to eliminate the fractions and then use the conventional method of solving first-degree equations.

In this article, we will look at several examples with answers to master this topic and we will also look at some practice problems and practice what we have learned.

## Summary of linear equations with fractions

Recall that, for an equation to be of the first degree, all the variables in the equation must have a maximum power of 1. For example, the equations and are first degree equations with fractions. We can solve first degree equations with fractions with the following steps:

Step 1: Remove the fractions: We multiply the entire equation by the least common multiple to remove the fractions.

Step 2: Simplify: We remove the parentheses and other grouping signs and combine like terms.

Step 3: Solve for the variable: We use addition and subtraction to move the variable to only one side of the equation.

Step 4: Solve: We use multiplication and division to solve for the variable completely.
