Question

the sum of two number is 65. the smaller number is 13 less than the large number. what are the numbers?

Answer 1

26 and 39

Explanation:

We translate this into an equation.

Let x = small number

Let y = big number.

x + y = 65

x = y - 13

Solve

plug in for x

(y - 13) + y = 65

y + y - 13 = 65

2y - 13 =65

2y = 78

y = 78/2

y = 39

x = 39 - 13 = 26
