Question

Stephen was thinking of a number. Stephen adds 2, then divides by 7 to get an answer of 11. What was the original number?

Answer 1

75

Explanation:

Let x = number thought of

(x + 2) / 7 = 11

multiply both sides of the equation by 7

11 x 7 = x+ 2

collect like terms

77 - 2 = x

x = 75
