The quotient of a number and five is eight less than the number. What is the number?

a. 2

b. 2

c. 3

d. 10

Answer is 2. based on the choices A or B.

x/5 = x - 8

5 (x/5) = 5 (x-8) * to remove the denominator of 5, multiply both sides by 5.

x = 5x - 40

x - 5x = - 40

-4x = - 40

-4x / - 4 = - 40 / - 4

x = 10

to check

x/5 = x - 8

10/5 = 10-8

2 = 2
