Answer:

(-1.5, -2)

Step-by-step explanation:

multiply the first equation by -8

-4x - 4 + 4y - 2 = -8

-4x + 4y = -2

multiply the second equation by 6

3y + y - 1 = 6x

6x - 4y = -1

Now add the 2 equations together

2x = -3

x = -1.5

plug that back in to solve for y

-4(-1.5) + 4y = -2

4y = -8

y = -2
