Question

The sum of x and y numbers is 20. The difference of the two numbers is 16. If the numbers are x and y, which system of linear equations represents the problem?
A.)x+y=20
x+y=20
B.)x+y=20
x+y=16
C.)x-y=20
x+y=16
D.)x-y=20
x-y=16

Answer 1

C

Answer 2

is there a typo?

Answer 3

no .

Answer 4

Well the question states the sum of the two numbers is 20.. that would imply
x + y = 20
The difference between the two numbers is 16.. which implies
x - y = 16

This system is not one of the choices....
