Answer:
(x, y) = (9, 5)
Step-by-step explanation:
We can add 4 times the second equation to the first to eliminate x:
(-4x +9y) +4(x -3y) = (9) +4(-6)
-3y = -15 . . . . . . simplify
y = -15/-3 = 5 . . . . divide by -3
__
Substituting that into the second equation, we can find x:
x -3(5) = -6
x = 9 . . . . . . . add 15
The ordered pair that satisfies both equations is ...
(x, y) = (9, 5)
