D=9x-54+2x
Use the distributive property to multiply 9 by x-6.
D=11x-54
Combine 9x and 2x to get 11x.
D=9x-54+2x
Use the distributive property to multiply 9 by x-6.
D=11x-54
Combine 9x and 2x to get 11x.
11x-54=D
Swap sides so that all variable terms are on the left hand side.
11x=D+54
Add 54 to both sides.
\frac{11x}{11}=\frac{D+54}{11}
Divide both sides by 11.
x=\frac{D+54}{11}
Dividing by 11 undoes the multiplication by 11.
