Solve 2x+y+4=0

$$2x+y+4=0$$

Solve for x

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

Steps for Solving Linear Equation

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

$$2x+4=-y$$

Subtract 4 from both sides.

$$2x=-y-4$$

Divide both sides by 2.

$$\frac{2x}{2}=\frac{-y-4}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$x=\frac{-y-4}{2}$$

Divide -y-4 by 2.

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

Solve for y

$$y=-2x-4$$

Solution Steps

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

$$y+4=-2x$$

Subtract 4 from both sides.

$$y=-2x-4$$
