Answer: x=4, y=-2

Explanation:

we can use the elimination method to eliminate one term to find x. Let multiply the top system by 4 then add the second system to eliminate the variable.

4(3x-y=14)

12x-4y=56

5x+4y=12

17x=68

x=4

Since we know x=4, let plug this back in to one of the system to find y.

5(4)+4y=12

20+4y=12

4y=-8

y=-2
