Question

The sum of positive integers b and h is 34. If their difference is 8, what is the value of bh

Answer 1

b + h = 34
b - h = 8 then b = h + 8

h + 8 + h = 34
2h + 8 = 34
2h = 34 - 8
2h = 26
h = 26/2
h = 13

b = h + 8
b = 13 + 8 = 21

Proof:
21 + 13 = 34
21 - 13 = 8

Value of bh = 21 * 8 = 168

Answer 2

The answer is 22 and 12!
