Question

$$y=5x+20$$

Solve for x

$x=\frac{y-20}{5}$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$5x+20=y$$

Subtract $20$ from both sides.

$$5x=y-20$$

Divide both sides by $5$.

$$\frac{5x}{5}=\frac{y-20}{5}$$

Dividing by $5$ undoes the multiplication by $5$.

$$x=\frac{y-20}{5}$$

Divide $y-20$ by $5$.

$$x=\frac{y}{5}-4$$
