What is the sum of two numbers is 37 and their difference is 7 find the numbers?

Answer 1

Answer:

22, 15.

Solution:

Suppose the first number is x, second one is y, then x + y = 37, x - y = 7.

adding these equations:

x + y = 37

+

x - y = 7

_____________

2 x + 0 = 44

x = 44/2 = 22

now substitute in first equation:

22 + y = 37

y = 37 - 22

y = 15

so the numbers are: 22 and 15.
