Question

Two numbers have a sum of 24, and 7 times the first number minus the second number is equal to 16. What is the smaller number?

Answer 1

Explanation:

Let the first number = x

Let the second number = y

x + y = 24

7x - y = 16 Add these two equations

8x = 40 Divide by 8

8x/8 = 40/8

x = 5

The smaller number will be 5

================

5 + y = 24

y = 19

==================

Proof

7*5 - 19 = 16

35 - 19 = 16
