How to solve x = 3 y - 4

1. Factor the equation (x + 2)(x + 3) = 0. 2. Set each factor equal to zero: x + 2 = 0 and x + 3 = 0. 3. Solve for x: x = -2 and x = -3.

Question

$$x = 3 y - 4$$

Solve for y

$y=\frac{x+4}{3}$

Steps for Solving Linear Equation

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

$$3y-4=x$$

Add $4$ to both sides.

$$3y=x+4$$

Divide both sides by $3$.

$$\frac{3y}{3}=\frac{x+4}{3}$$

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

$$y=\frac{x+4}{3}$$
