Solve z=1-2y/2

$$z = \frac { 1 - 2 y } { 2 }$$

Solve for y

$$y=\frac{1}{2}-z$$

Steps for Solving Linear Equation

Divide each term of 1-2y by 2 to get \frac{1}{2}-y.

$$z=\frac{1}{2}-y$$

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

$$\frac{1}{2}-y=z$$

Subtract \frac{1}{2} from both sides.

$$-y=z-\frac{1}{2}$$

Divide both sides by -1.

$$\frac{-y}{-1}=\frac{z-\frac{1}{2}}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$y=\frac{z-\frac{1}{2}}{-1}$$

Divide z-\frac{1}{2} by -1.

$$y=\frac{1}{2}-z$$

Solve for z

$$z=\frac{1}{2}-y$$

Solution Steps

Divide each term of 1-2y by 2 to get \frac{1}{2}-y.

$$z=\frac{1}{2}-y$$
