Question

The sum of two numbers is 85. There difference is 9. Find the numbers​

Answer 1

Represent the numbers as expressions.
number 1 - n
number 2 - n + 9

Isolate “n.”
n + n + 9 = 85
2n + 9 = 85
2n = 85 - 9
n = 76/2
n = 38

Determine the numbers by substituting the n value into the expressions.

1. n = 38
2. n + 9 = 38 + 9 = 47

Therefore the numbers are 38 and 47.

Answer 2

38 and 47

Explanation:

The first number would be = (85-9)/2

= 76/2 = 38

The second number would be either 85 - 38 or 38 + 9 = 47
