#### Answer

(3,-2)

#### Work Step by Step

x + 3y = -3
2x + y = 4
x + 3y = -3
y = 4-2x (subtracted 2x from both sides)
x+3(4-2x)=-3 (subsituted y = 4-2x, into x + 3y = -3 )
x+12-6x=-3
-5x=-15 (subtracted 12 from both sides)
x=3 (divided both sides by -5)
2(3) + y = 4
6+y=4
y=-2 (subtracted 6 from both sides leaving -2)
(3,-2)
Check if it is correct by plugging it into x + 3y = -3
3 +3(-2)=-3
3-6=-3
-3=-3
