    ok, so our equation is 4x - 5y = 9 start by subtracting 4x from each side

    -5y = 9 - 4x the 9 and the 4x cannot be put together to get 5x, since 9 is a number and 5x is a variable

    recall that 4x means: x+x+x+x 9-x-x-x-x is not the same as 5x, or x+x+x+x+x

    -5y = 9 - 4x dividing both sides by -5 gives us y = (9-4x)/(-5)
