Question

Ax+by=c, how would I solve for y

Answer 1

Solving for y means trying to get the equation into the form y= _____.  So, let's say that we are going to keep the y value on the left side of the equation.  

First, we would subtract ax from both sides.  This results in the equation by=c-ax.

Next, we figure out that y has a coefficient of b.  They are combined together by multiplication, so to undo this operation, we need to divide both sides by b.  

If done correctly, your final answer should be$\frac{c-ax}{b}$.  Or, y=c-ax/b
