Question

The sum of two numbers is 18 and the difference is 4

Answer 1

I Think The Answer Is 14

18-4=14


Hope This Helps.

Answer 2

Let x represent the first number
Let y represent the second number

x + y = 18
x - y = 4

Use elimination method to solve this system of equations:
2x = 22
x = 11

Plug the x-value into one of the original equations to solve for y:
x - y = 4
(11) - y = 4
y = 7

The two numbers are 7 and 11
