648-36\times 8=\left(36+4\right)x
Multiply 36 and 18 to get 648.
648-288=\left(36+4\right)x
Multiply 36 and 8 to get 288.
360=\left(36+4\right)x
Subtract 288 from 648 to get 360.
360=40x
Add 36 and 4 to get 40.
40x=360
Swap sides so that all variable terms are on the left hand side.
x=\frac{360}{40}
Divide both sides by 40.
x=9
Divide 360 by 40 to get 9.
