Question

The sum of two numbers is 66. The difference of the same two number is 38. What are the numbers?

Answer 1

37 and 29

Explanation:

x + y = 66

x - y = 8

*******************************************

solve second equation for x

x = y + 8

substitute for x in first equation

y+8 +y = 66

2y = 58

y = 29

*******************************************

x - 29 = 8

x = 37

******************************************

x = 37 and y = 29
