so our starting problem is 5x-3y=9

you want to move the x variable to the right

so then it would be -3y=9-5x

the next step would be to divide both sides of the equation by -3 to get y by itself

that would give you y=-3+5/3x

then use the commutative property to rearrange the terms giving you the answer

y=5/3x-3

Start by isolating all y terms, then simplifying to solve for y.

5x - 3y = 9
5x - 3y + 3y = 9 + 3y
5x = 9 + 3y
5x - 9 = 9 + 3y - 9
5x - 9 = 3y
5x/3 - 9/3 = 3y/3
y = 5x/3 - 3
