Answer 5

What if I multiplied a number by the first equation?

Answer 12

Here's what I did:

x + y = 8
-10(x) + -10(y) = -10(8)
-10x - 10y = -80
_____________________________________________________________________________
-10x - 10y = -80
+
12x + 10y = 86
=
2x + 0 = 6
2x = 6
2x/2 = 6/2
x = 3
_____________________________________________________________________________
3 + y = 8
3 + y - 3 = 8 - 3
y = 5

Solution: (3, 5)
