When you solve equations, the goal is to find a number that would make the equation true if you replaced the variable with it. That number is called a solution of the equation. The method you use to find the solution depends on what type of equation you are solving.

## Types of Equations

### Linear

Equations

Linear equations do not have any terms with exponents like \(x^2\). They also do not have any roots like \(\sqrt{x}\).

\[3x-1=5\]

\[4x-x+6=2x-1\]

\[\frac{x}{4}+\frac{3}{5}=8\]

### Quadratic

Equations

Quadratic equations have terms \(x^2\) and \(x\) but no

\[3x-1=5\]

\[4x-x+6=2x-1\]

\[\frac{x}{4}+\frac{3}{5}=8\]

### Exponential

Equations

Exponential equations have variables in the exponent of an expression.

\[3x-1=5\]

\[4x-x+6=2x-1\]

\[\frac{x}{4}+\frac{3}{5}=8\]
