Let's call x the number.
You know that if you triple the sum of x and 3, you get a value that is 9 less than twice the number x.
This means that you can write
( x + 3 ) 3 three times the sum of x and 3 = 2 x - 9 9 less than twice the value of x
Rearrange the above equation to solve for x
3x+9=2x−9
3x−2x=−9−9
x=−18
