Question

10. The sum of two numbers is 102. One number is three less than twice the other.

What are the two numbers?

Answer 1

(2n -3) + n = 102

2n - 3 + n = 102

3n - 3 = 102

3n = 105

n = 35 (the first number)

SO...

The other number is (2 x 35) - 3 =

70 - 3 = 67 (the second number)

The numbers are 35 and 67.

35 + 67 = 102 CHECK!
