I have a math question. Right before the winter break we started working on solving formulas/equations for a specified variable. Here are some examples so far (answers in parenthesis):

d=rt, solve for t

(d/r=t)

3x + 4y= 12, solve for y

(y= -3x + 12/4)

f=v + at, solve for t

(t= f - v/a)

This is what I'm not sure how to do:

2x - 3y + 7, solve for y

The other problems have an equal sign. I can't find anything in my text book about this. Is it possible to solve for "y" without there being an equal sign?
