Answer:

(x, y) = (5, 4)

Explanation:

Subtracting the second equation from the first eliminates the x term.

(4x +6y) -(4x +2y) = (44) -(28)

4y = 16 . . . . simplify

y = 4

Using the second equation to find x, we have ...

4x +2(4) = 28

x + 2 = 7 . . . . . . divide by 4

x = 5 . . . . . . . . . subtract 2

The solution is (x, y) = (5, 4).
