Solve x+2y+12=0

$$x + 2 y + 12 = 0$$

Solve for x

$$x=-2y-12$$

Solution Steps

Subtract 2y from both sides. Anything subtracted from zero gives its negation.

$$x+12=-2y$$

Subtract 12 from both sides.

$$x=-2y-12$$

Solve for y

$$y=-\frac{x}{2}-6$$

Steps for Solving Linear Equation

Subtract x from both sides. Anything subtracted from zero gives its negation.

$$2y+12=-x$$

Subtract 12 from both sides.

$$2y=-x-12$$

Divide both sides by 2.

$$\frac{2y}{2}=\frac{-x-12}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$y=\frac{-x-12}{2}$$

Divide -x-12 by 2.

$$y=-\frac{x}{2}-6$$
