-3x%2B7=2y%2B3 Start with the given equation.


-3%284%29%2B7=2y%2B3 Plug in x=4


-12%2B7=2y%2B3 Plug in x=4


-5=2y%2B3 Combine like terms on the left side.


0=2y%2B3%2B5 Add 5 to both sides.


-2y=3%2B5 Subtract 2y from both sides.


-2y=8 Combine like terms on the right side.


y=%288%29%2F%28-2%29 Divide both sides by -2 to isolate y.


y=-4 Reduce.
