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