Answer:

(x, y) = (7, -7)

Step-by-step explanation:

You can eliminate y by adding the two equations:

(3x -y) +(3x +y) = (28) +(14)

6x = 42 . . . . simplify

x = 7 . . . . . . divide by 6

You can eliminate x by subtracting the two equations:

(3x +y) -(3x -y) = (14) -(28)

2y = -14 . . . . simplify

y = -7 . . . . . . divide by 2

The solution is (x, y) = (7, -7).
