length of a rectangle is five more than three times a number:  L = 5 + 3x = 3x + 5
 
width is 3 less than twice the number:  W = -3 + 2x = 2x - 3
 
find the area:  A = LW = (3x + 5)(2x - 3)
 
The words of the problem statement were translated correctly into algebra, and the formula for area of a rectangle was applied correctly.  There is nothing wrong with this solution.
