Question

$$y=-3x-4.Para.-3 < x < -1$$

Solve for x

$x=\frac{-y-4}{3}$

Steps for Solving Linear Equation

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

$$-3x-4=y$$

Add $4$ to both sides.

$$-3x=y+4$$

Divide both sides by $-3$.

$$\frac{-3x}{-3}=\frac{y+4}{-3}$$

Dividing by $-3$ undoes the multiplication by $-3$.

$$x=\frac{y+4}{-3}$$

Divide $y+4$ by $-3$.

$$x=\frac{-y-4}{3}$$

Solve for y

$y=-3x-4$
