6y=9-3x rearrange for x=
Change 6y = 9 - 3x to:
3x = -6y + 9, then solve for x by dividing both sides by 3 to get:
x = -2y + 3
when you divided both sides by 3. there is a rule where you cant divide the answer if theirs an addition sign.
so
3x=-6y+9
x=(-6y+9)all over 3
you cant simplify it more than that
