Let x = the number

 

"Fifteen more than" means addition

 

"Three times a number" is multiplication

 

"three less than" is subtraction, as is the term difference

 

Putting it all together, we have

 

7 - (15 + 3x) = (9 - 5x) - 3

 

-8 + 3x = 6 - 5x

 

-8 = 6 - 8x

 

-14 = -8x

 

14/8 = 7/4 = x
