A=6x-15
Use the distributive property to multiply 3 by 2x-5.
6x-15=A
Swap sides so that all variable terms are on the left hand side.
6x=A+15
Add 15 to both sides.
\frac{6x}{6}=\frac{A+15}{6}
Divide both sides by 6.
x=\frac{A+15}{6}
Dividing by 6 undoes the multiplication by 6.
x=\frac{A}{6}+\frac{5}{2}
Divide A+15 by 6.
A=6x-15
Use the distributive property to multiply 3 by 2x-5.
