Use the distributive property on: 3(5x + 1) + 5(3x  2) Which is your numerator. a(c + d) = ac + ad You will get 2 terms that will cancel and 2 other terms that can be combined.

That is now for you to show it. You should show your work now instead of me because that is sufficient help for you to at least start to try to solve it. Go ahead now. It's your problem so take ownership and do some work.

You did well on the first half, but: 5(3x  2) is not equal to 5x + 10 the "10" is right but concentrate on the "5x". That is where you went wrong a little bit.

You have 5 times 3x There is a negative sign involved. Always check your signs.

Yes. So, your numerator is : 15x + 3 + 15x + 10 so far. So now, 2 of the terms will cancel and the other 2 can be combined.

ok so 15x and 15x will cancel and we will combine 10 and 3 to get 13 :)
