Question

6x+4=-39
3x+2y=-15
solve for y. i thought it was 18.. but i need clarifacation with these problems.

Answer 1

I think you meant

6x+4y = -39

right?

Answer 2

so sorry. 6x+y=-39. just y.

Answer 3

6x + y = -39
3x + 2y = -15
Multiply the second equation by -3 then add both equations together.

6x + y = -39
-6x - 4y = 30

Answer 4

Add the equations together. The x's will add up to zero and will cancel out, and you'll have an equation with only y. then you can easily solve for y.
