Solve 4-y=2x?

$$4 - y = 2 x ?$$

Solve for x

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

Steps for Solving Linear Equation

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

$$2x=4-y$$

Divide both sides by 2.

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

Dividing by 2 undoes the multiplication by 2.

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

Divide 4-y by 2.

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

Solve for y

$$y=4-2x$$

Steps for Solving Linear Equation

Subtract 4 from both sides.

$$-y=2x-4$$

Divide both sides by -1.

$$\frac{-y}{-1}=\frac{2x-4}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$y=\frac{2x-4}{-1}$$

Divide -4+2x by -1.

$$y=4-2x$$
