Introduction to Equations

Equations with variables have solutions, or values for the variables that make the statements true.

The addition and multiplication properties of equalities are common ways used to solve equations.

A rational equation sets two rational expressions equal to each other and involves unknown values that make the equation true.

Equations involving radicals are often solved by moving the radical to one side of the equation and then squaring both sides.

To solve an equation with an absolute value, first isolate the absolute value, and then solve for the positive and negative cases.
