Answer 3

Sorry, I was wrong. Looking at the answers given it looks like what you need to do is solve for y.

So the equation is
\[435x+5y-125=0\]
So the easiest way to do this would be to subtract 5y from both sides
\[435x-125=-5y\]
Then divide both sides by 5.

Answer 4

so would it be A?? @PsychoTink
