THE ANSWER IS NOT 15

The answer is -3.75

Here's how i worked it out:

5(y-3) / 3y =3

multiply out brackets

5y-15 / 3y =3

multiply everything by 3y to remove fraction

5y-15=9y

move y's to one side of the equation

-15=9y-5y

so

4y=-15

then y on its own is

y= -15 / 4

therefore

y=-3.75

If you put 15 in the original equation, you get 1.333, not 3

Im not sure if thats correct alex because u would have to Times y by 5 which would be -18.5 so you couldnt really get 3 from that im affraid.

Im not sure on the correct answer however.

Not correct alex.

Concentric was right, but when you simplify it, it becomes 1.5.

But if u put -3.75 into the equation:

5(-3.75-3) / 3*-3.75 = 3

5*-6.75 / -11.25 = 3

-33.75 / -11.25 = 3

Sorry, the answer is 15

I was using the equation 5(y-3) / 3y = 3 instead of 5(2y-3) / 3y = 3

My bad
