You want to do the same thing to both sides of the equation. For instance, we can subtract 4x from both sides.
. Subtract 4x from both sides. Now we have
, which is answer choice d or b. These two are really the same answer because by the commutative property. The answer is NOT c however.

The other tutor's answer is wrong for the x-term must come first.

3y = 4x + 9

To get the 3-term standard form we get the constant only 
on the right, the x term first on the left and the y-term
after the x term on the left:

-4x + 3y = 9  choice b)

The correct equation in standard form will
have the following form:
Ax + By = C.
Look at the list of equations.
Which one has the form (number)x + (number)y = C?
The answer is C. Do you agree? Do you understand why?
