Answer 1

A

Explanation:

Answer 2

(x, y) = (-4, -15)

Explanation:

You can equate the expressions for y and solve for x.

3/4x -12 = -4x -31

Adding 4x+12 gives ...

(4 3/4)x = -19

(19/4)x = -19

Multiplying by 4/19, we find ...

x = -4

Substituting that into the first equation, we can find y:

y = (3/4)(-4) -12 = -15

The solution is (x, y) = (-4, -15).
