A=-18x+12
Use the distributive property to multiply -6 by 3x-2.
-18x+12=A
Swap sides so that all variable terms are on the left hand side.
-18x=A-12
Subtract 12 from both sides.
\frac{-18x}{-18}=\frac{A-12}{-18}
Divide both sides by -18.
x=\frac{A-12}{-18}
Dividing by -18 undoes the multiplication by -18.
x=-\frac{A}{18}+\frac{2}{3}
Divide A-12 by -18.
A=-18x+12
Use the distributive property to multiply -6 by 3x-2.
