140=7\left(x-8\right)
Variable x cannot be equal to 8 since division by zero is not defined. Multiply both sides of the equation by x-8.
140=7x-56
Use the distributive property to multiply 7 by x-8.
7x-56=140
Swap sides so that all variable terms are on the left hand side.
7x=140+56
Add 56 to both sides.
7x=196
Add 140 and 56 to get 196.
x=\frac{196}{7}
Divide both sides by 7.
x=28
Divide 196 by 7 to get 28.
