Solve 2x+y2+1=0

$$2x+y2+1=0$$

Solve for x

$$x=\frac{-y_{2}-1}{2}$$

Steps for Solving Linear Equation

Subtract y_{2} from both sides. Anything subtracted from zero gives its negation.

$$2x+1=-y_{2}$$

Subtract 1 from both sides.

$$2x=-y_{2}-1$$

Divide both sides by 2.

$$\frac{2x}{2}=\frac{-y_{2}-1}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$x=\frac{-y_{2}-1}{2}$$

Solve for y_2

$$y_{2}=-2x-1$$

Solution Steps

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

$$y_{2}+1=-2x$$

Subtract 1 from both sides.

$$y_{2}=-2x-1$$
