Question

$$y=-x+4$$

Solve for x

$x=4-y$

Steps for Solving Linear Equation

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

$$-x+4=y$$

Subtract $4$ from both sides.

$$-x=y-4$$

Divide both sides by $-1$.

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

Dividing by $-1$ undoes the multiplication by $-1$.

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

Divide $y-4$ by $-1$.

$$x=4-y$$

Solve for y

$y=4-x$
