# Simplify the following expression: 10x - 12x.

## Question:

Simplify the following expression: {eq}10x - 12x {/eq}.

## Algebraic Expressions

An algebraic expression is made of algebraic terms separated by mathematical operations like addition, multiplication, subtraction and division. An algebraic term is made up of constants and variables.

## Answer and Explanation:

In the simple algebraic expression below, the terms already have the same variables so the mathematical operation can be executed. The coefficients of the variable {eq}x {/eq} will be subtracted, leaving the variable unchanged:

{eq}10x - 12x {/eq}

{eq}-2x {/eq}

Thus, the expression {eq}10x - 12x {/eq} in simplified form is {eq}-2x {/eq}.
