15 + 3 • 6 ÷ x = 24

I know the answer is 2, but i can't for the life of me show the work for my teacher. I subtract 15 from both sides and get

3•6÷x= 9

then I have tried multiplying 3 • 6 to get 18 ÷ x = 9

of course when you multiply the the 18 of to the 9 x does not equal 2.

What am i doing wrong in my work. Looking at the problem i know i need to get x to equal 2. I just can't figure out how.
