Answer:
(6,-2)
Step-by-step explanation:
2x + 3y = 6
x + y = 4
Multiply the second equation by -2 to eliminate x
-2(x+y) = -2*4
-2x-2y = -8
Add this to the first equation
2x + 3y = 6
-2x -2y = -8
---------------------
y = -2
Now we need to find x
x+y = 4
x-2 = 4
Add 2 to each side
x-2+2 = 4+2
x = 6
