Answer:
y = - 9/2
Explanation:
2y - 3 = 4y + 6
-6 -6 *subtract 6 from both sides of the equation, which is the opposite operation
2y - 9 = 4y * your sixes cancel out leaving you w/ the current equation; next you subtract 2y from each side.
2y - 9 = 4y
-2y -2y
* now you are left with: -9 = 2y; so you do the opposite operation (again) and divide both sides by 2. Your twos cancel out leaving you with y = -9/2.
