y=3\left(-3-2x\right)
Subtract 7 from 4 to get -3.
y=-9-6x
Use the distributive property to multiply 3 by -3-2x.
-9-6x=y
Swap sides so that all variable terms are on the left hand side.
-6x=y+9
Add 9 to both sides.
\frac{-6x}{-6}=\frac{y+9}{-6}
Divide both sides by -6.
x=\frac{y+9}{-6}
Dividing by -6 undoes the multiplication by -6.
x=-\frac{y}{6}-\frac{3}{2}
Divide y+9 by -6.
y=3\left(-3-2x\right)
Subtract 7 from 4 to get -3.
y=-9-6x
Use the distributive property to multiply 3 by -3-2x.
