A=15x-2+6
Combine 5x and 10x to get 15x.
A=15x+4
Add -2 and 6 to get 4.
A=15x-2+6
Combine 5x and 10x to get 15x.
A=15x+4
Add -2 and 6 to get 4.
15x+4=A
Swap sides so that all variable terms are on the left hand side.
15x=A-4
Subtract 4 from both sides.
\frac{15x}{15}=\frac{A-4}{15}
Divide both sides by 15.
x=\frac{A-4}{15}
Dividing by 15 undoes the multiplication by 15.
