Answer:

(x, y) = (-2, -3)

WORK:

2x + 4y = -16 =

-2x + 2y = -2 =

(^ the two’s cancel out) =

6y = -18 =

(^ you need to divide 6 on both sides to get just y) =

6y/6 = -18/6 =

(^ the six’s cancel out) =

y = -3 =

(^ now you have to plug this in to get x) =

2x + 4(-3) = -16 =

2x - 12 = -16 =

(^ you need to add 12 on both sides to get rid of it on the left side to add it to -16 on the right side) =

2x = -4 =

2x/2 = -4/2 =

(^ now you divide 2 on both sides again to get just y, and they will cancel out) =

x = -2 =

THEREFORE YOU GET (-2, -3)
