y+6=-3\left(x+2\right)
Anything divided by one gives itself.
y+6=-3x-6
Use the distributive property to multiply -3 by x+2.
-3x-6=y+6
Swap sides so that all variable terms are on the left hand side.
-3x=y+6+6
Add 6 to both sides.
-3x=y+12
Add 6 and 6 to get 12.
\frac{-3x}{-3}=\frac{y+12}{-3}
Divide both sides by -3.
x=\frac{y+12}{-3}
Dividing by -3 undoes the multiplication by -3.
x=-\frac{y}{3}-4
Divide y+12 by -3.
y+6=-3\left(x+2\right)
Anything divided by one gives itself.
y+6=-3x-6
Use the distributive property to multiply -3 by x+2.
y=-3x-6-6
Subtract 6 from both sides.
y=-3x-12
Subtract 6 from -6 to get -12.
