Gather like terms. The - 2 and 4; the 7n and 3n. 7n - 2 + 3n + 4 = 10n + 2
3n+2+3n+2=6n+4
All you do is look for like terms such as 7n and 3n; 2 and 8 Then you do 7n+3n=10 n And ........... 2-8=-6 The answer is 10n-6 if you still dont get it contact me(:
well the first four terms are n=1,2,3 and 4 so just substitute those numbers into k=3n so k= 3,6,9,12
first combine like terms and 5n+7=-41 add -7 to both sides 5n=-48 n=-48/5
