3n+6=18 n+2=6 n=4
8 + 3(6) = 8 + 18 = 26
3n + 4n = 42 7n = 42 n = 42/7 n = 6
It depends! What is the value of N? Example If n= 3, the answer would be 11 (3n= 3x3=9 the plus the 2) Example 2 If n=7, ten the answer would be 23 (3n= 3x7=21 plus the 2wouldbe 23) Hope this helps
3n + 14 = 83n = 8 - 14 = -63n/3 = -6/3n = -2The value of n is -2.
