Rearrange before substitution:
7x - y = -5
Would it be: -y= 5 - 7x?

Yes.
How would you plug it into 5x - 3y = 1
Would it be: 5x - 3(-5 - 7x) = 1?
Would it be: 5x - 3(-5 - 7x) = 1?
We'll, this is the whole problem:
Use substitution to solve for x and y:
{5x - 3y =1
{7x - y = -5
The answer is suppose to be (-1,-2)
