Question

find two number with a sum of 5,256 and a difference of 2,142?

Answer 1

x + y = 5256

x - y = 2142

Then subtract the equations from eachother to eliminate the X value

(x+y) - (x - y) =
5256 - 2142 = 3114.

Now, from there, your equation is 2y = 3114, making y=1557

Now, put that in your original equation (either one will work).

5256-1557= 3699. x= 3699.

Test:
3699+1557= 5256
3699-1557= 2142
