Question

I'm working on solving a system of equations by substitution.
The two equations given are these:
-4.5x - 2y = -12.5
3.25x - y = -0.75
I need to flip the equation 3.25x - y = -0.75 so that I can substitute it into my other equation. How should I flip it? I get confused about whether I should change signs, drop negatives, etc., so I don't know what to carry and drop and such when flipping. I think it should be y = -0.75 + 3.25x but I feel like I'm probably wrong, so can anyone help me out?

so
you want to solve this for y
