Solve 15-y=2x-8

$$15 - y = 2 x - 8$$

Solve for x

$$x=\frac{23-y}{2}$$

Steps for Solving Linear Equation

Swap sides so that all variable terms are on the left hand side.

$$2x-8=15-y$$

Add 8 to both sides.

$$2x=15-y+8$$

Add 15 and 8 to get 23.

$$2x=23-y$$

Divide both sides by 2.

$$\frac{2x}{2}=\frac{23-y}{2}$$

Dividing by 2 undoes the multiplication by 2.

$$x=\frac{23-y}{2}$$

Solve for y

$$y=23-2x$$

Steps for Solving Linear Equation

Subtract 15 from both sides.

$$-y=2x-8-15$$

Subtract 15 from -8 to get -23.

$$-y=2x-23$$

Divide both sides by -1.

$$\frac{-y}{-1}=\frac{2x-23}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$y=\frac{2x-23}{-1}$$

Divide 2x-23 by -1.

$$y=23-2x$$
