Solve x_{1}+2x-y=-36

$$x _ { 1 } + 2 x - y = - 36$$

Solve for x

$$x=\frac{-x_{1}+y-36}{2}$$

Steps for Solving Linear Equation

Subtract x_{1} from both sides.

$$2x-y=-36-x_{1}$$

Add y to both sides.

$$2x=-36-x_{1}+y$$

The equation is in standard form.

$$2x=-x_{1}+y-36$$

Divide both sides by 2.

$$\frac{2x}{2}=\frac{-x_{1}+y-36}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$x=\frac{-x_{1}+y-36}{2}$$

Divide -36-x_{1}+y by 2.

$$x=\frac{y}{2}-\frac{x_{1}}{2}-18$$

Solve for x_1

$$x_{1}=-2x+y-36$$

Solution Steps

Subtract 2x from both sides.

$$x_{1}-y=-36-2x$$

Add y to both sides.

$$x_{1}=-36-2x+y$$
