1.) write your equation: 18=4n + 6 (we don't know what # is multiplied by 4, so we can use a variable there as a substitute)
2.) Subtract 6 on both sides since it is positive 6
18=4n+6
-6 -6 (the 6 on the right will cancel out bc one is pos. and the other is neg.)
3.) 18-6=12
4.) now all you have left is: 12=4n (divide 4 on both side since it has a variable next to it)
5.) 4 divided by 4 will cancel and 12divided by 4 will be 3.
ANSWER: 3
6.) Check by plugging in your answer. 3*4 + 6 =18
