Question

The sum of two numbers is 82. One number is three less than four times the other. Find the two numbers.

Answer 1

17 , 65

Explanation:

x+ y = 82

y = 4x - 3

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

Put the second equation into the first.

x + 4x - 3 = 82

5x = 85

x = 85/5

x = 17

17 + y = 82

x = 82 - 17

x = 65
