Solve -y-3=-3x

$$- y - 3 = - 3 x$$

Solve for x

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

Steps for Solving Linear Equation

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

$$-3x=-y-3$$

Divide both sides by -3.

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

Dividing by -3 undoes the multiplication by -3.

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

Divide -y-3 by -3.

$$x=\frac{y}{3}+1$$

Solve for y

$$y=3\left(x-1\right)$$

Steps for Solving Linear Equation

Add 3 to both sides.

$$-y=-3x+3$$

The equation is in standard form.

$$-y=3-3x$$

Divide both sides by -1.

$$\frac{-y}{-1}=\frac{3-3x}{-1}$$

Dividing by -1 undoes the multiplication by -1.

$$y=\frac{3-3x}{-1}$$

Divide -3x+3 by -1.

$$y=3x-3$$
