Solve for x 3x-4y=-12

$3 x - 4 y = - 12$

Step 1

Add $4 y$ to both sides of the equation.

$3 x = - 12 + 4 y$

Step 2

Divide each term in $3 x = - 12 + 4 y$ by $3$ and simplify.

Divide each term in $3 x = - 12 + 4 y$ by $3$ .

$\frac{3 x}{3} = \frac{- 12}{3} + \frac{4 y}{3}$

Simplify the left side.

Cancel the common factor of $3$ .

Cancel the common factor.

$\frac{3 x}{3} = \frac{- 12}{3} + \frac{4 y}{3}$

Divide $x$ by $1$ .

$x = \frac{- 12}{3} + \frac{4 y}{3}$

Simplify the right side.

Divide $- 12$ by $3$ .

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