# Solving One-Step Linear Equations with Mixed Numbers: Subtraction

While it''s common to encounter linear equations with multiple operations, some linear equations can be solved with a single operation. Let''s take a look at the process of solving one-step linear equations that involve subtraction and mixed numbers.

## How to subtract one-step linear equations with mixed numbers

Before outlining the process of solving a one-step linear equation with subtraction, let''s go over the mixed number.

A mixed number is expressed as the sum of a whole number and a fraction (ex. 2 1/5). While mixed numbers give a better idea of the size of a number, making calculations is easier with improper fractions. For this reason, we''ll convert mixed numbers into improper fractions to solve one-step linear equations that involve subtraction.

Let''s get started!

Solve the following one-step linear equation:

First, convert the mixed number into an improper fraction by writing the mixed number as a sum of a whole number and proper fraction. Then, write those parts with common denominators.

Your new linear equation is:

Now, we''ll use the inverse operation of subtraction to solve. Use the addition property of equality to add

Simplify.

Divide the numerator and the denominator by the greatest common factor, 2 to put the fraction in lowest terms.

## Practice questions on subtracting one-step linear equations with mixed numbers
