Four less than three times a number is three more than
two times the number.  What is the number?

Four less than three times a number is three more than 
two times the number.  

Use numerals for the spelt-out numbers

   4 less than 3 times a number is 3 more than 
   2 times the number

Replace the words "a number" and "the number" by N

   4 less than 3 times N is 3 more than 2 times N

Replace the words " 3 times N " by 3N and 
replace the words " 2 times N " by 2N

   4 less than 3N is 3 more than 2N

Replace the word " is " by " = "

   4 less than 3N = 3 more than 2N

To make 3N less you subtract from it, so replace 
the words " 4 less than 3N " by " 3N - 4 "

           3N - 4 = 3 more than 2N

Finally, to make 2N more, you add to it, 
so replace the words " 3 more than 2N " by " 2N + 3 "

           3N - 4 = 2N + 3

Can you solve that for N?  If not post again asking 
how to.

Answer: N = 7
