Answer:

(-4, 5)

Step-by-step explanation:

12x + 14y = 22

12x - 3y = -63

Rewrite the first equation. Multiply both sides of the second equation by -1 and write it below the first equation. Then, add the equations.

        12x + 14y = 22

(+)    -12x + 3y = 63

---------------------------

                 17y = 85

17y/17 = 85/17

y = 5

Substitute y with 5 in the first original equation and solve for x.

12x + 14y = 22

12x + 14(5) = 22

12x + 70 = 22

12x = -48

x = -4

Answer: (-4, 5)
