Kirk bought songs for his mp3 player. he needed 6 more songs to have a total of 100. write an integer to represent how many more songs kirk needs. i need !

This is very easy to solve once you understanding writing equations. In this case, we could do n+6=100 because we know that the number of songs he has now (n) plus 6 will equal 100. Below is a solution for this equation.

n+6=100
   -6     -6
n=94

After solving our equation, we know that Kirk has 94 songs.
