Four less than the quotient of a number and 4 is 14. What is the number? Let n be the unknown number.
Maru [420]
So the equation is n/4-4=14
then you +4 to both sides 
n/4-4=14 so now the equation is n/4=18 then you multiply 18 by 4 and get 72
   +4    +4
then to check your work
72/4-4=14
so N=72
Hope I helped :)
