These questions are easy to sometimes just go backwards.
Take 18*2=36
36-3=33
33/3=11
The number you want is 11.

You just need to create an equation from the words. Start with one piece and slowly add to it. Take it one step at a time:
"Three times some number" (3%2Ax)
"plus 3" (3x%2B3)
"divided by 2" (%283x%2B3%29%2F2)
"is equal to 18." (%283x%2B3%29%2F2=18)
Find the number.
.
%283x%2B3%29%2F2=18
3x%2B3=36
3x=33
x=11
