Do you want to solve for y?

3y=15x-12 Start with the given equation.


y=%2815x-12%29%2F%283%29 Divide both sides by 3 to isolate y.


y=%2815x%29%2F%283%29-%2812%29%2F%283%29 Break up the fraction.


y=5x-4 Reduce.

Answer:

So the answer is y=5x-4





Or....

Do you want to solve for x?


3y=15x-12 Start with the given equation.


0=15x-12-3y Subtract 3y from both sides.


-15x=-12-3y Subtract 15x from both sides.


x=%28-12-3y%29%2F%28-15%29 Divide both sides by -15 to isolate x.


x=%28-12%29%2F%28-15%29-%283y%29%2F%28-15%29 Break up the fraction.


x=4%2F5%2By%2F5 Reduce.


x=y%2F5%2B4%2F5 Rearrange the terms.
----------------------------------------------------------------------

Answer:

So the answer is x=y%2F5%2B4%2F5
