-A=-6x+3-6
Subtract 6 from both sides.
-A=-6x-3
Subtract 6 from 3 to get -3.
\frac{-A}{-1}=\frac{-6x-3}{-1}
Divide both sides by -1.
A=\frac{-6x-3}{-1}
Dividing by -1 undoes the multiplication by -1.
A=6x+3
Divide -6x-3 by -1.
-6x+3=6-A
Swap sides so that all variable terms are on the left hand side.
-6x=6-A-3
Subtract 3 from both sides.
-6x=3-A
Subtract 3 from 6 to get 3.
\frac{-6x}{-6}=\frac{3-A}{-6}
Divide both sides by -6.
x=\frac{3-A}{-6}
Dividing by -6 undoes the multiplication by -6.
x=\frac{A}{6}-\frac{1}{2}
Divide 3-A by -6.
