  3. Evaluate: sqrt()[ 4 ] /(-81)-16

Expression: $$y = 3 x - 5$$

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

$$3x-5=y$$

Add $5$ to both sides.

$$3x=y+5$$

Divide both sides by $3$.

$$\frac{3x}{3}=\frac{y+5}{3}$$

Dividing by $3$ undoes the multiplication by $3$.

$$x=\frac{y+5}{3}$$
