Answer:

(-4, 1)

Step-by-step explanation:

Solve it as a system of equations:

$3x-2y=-14\\3x+y=-11$

subtract the two equations

$-3y = -3$

divide both sides by -3

$y=1$

Plug this into the equation 3x + y = -11 to solve for x

$3x + 1 = -11\\$

subtract 1 from both sides

$3x = -12$

divide both sides by 3

$x = -4$

So the answer is (-4, 1)
