It's quite simple really :)
What do 10 and 15 have in common? 5.
10 / 5 = 2
15 / 5 = 3
So you times 2 by 5 to get 10, and 3 by 5 to get 15!
Put 5 outside the brackets, and then put the two numbers inside the brackets. Since it's 10x, you know you will have to write 2x inside the brackets, and since it's -15, you have to write -3 (not +3!)
So the answer would be: 5(2x-3)
Check it by solving the equation - multiplying out of the brackets :)
