Answer:

(9,3)

Step-by-step explanation:

Use elimination to solve.

-2 (-3x + 3y = -18)

6x - 6y = 36

-6x - 3y = -63

The 6x and -6x are eliminated and you are left with -9y = -27 when you combine -6y and -3y, and 36 - 63.

y = 3

Then, substitute 3 into either equation to find x

-3x + 3(3) = -18

-3x + 9 = -18

-3x = -27

x = 9
