Some other people may have been a bit hard on you. You've been quite
honest that this is a homework problem, and it's O.K. to ask for a bit
of guidance if you're stuck. Although Frederick Williams has written
out the whole answer, try to see how he got it so that you can handle
other problems like this one.
The original left-hand side is 2x + 4y but you want to change it
to just plain y. The two steps are first to move away the term 2x,
then to get rid of the coefficient 4. That first step requires
subtracting something from both sides of the equation, and the second
requires dividing both sides by something. See how Frederick did it.
Now, to make sure you've got the idea, I suggest you try another
similar problem; say, transform 6x - 2y = 10 into slope-intercept
form. Remember the coefficient of y is now (-2).
There may be similar practice exercises in your text-book. You
should soon be able to handle them quite quickly.
