3n + 4n = -14 7n /7 = -14 /7 n = -2
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
3 + 3n = 9 + 2n + 4n n = -2
It is 12n2 + 3n - 58
3n + 4n = -14 7n /7 = -14 /7 n = -2
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
-n + 4n = 4n - n = 3n Done!!!!!
If you mean: n-3n = 14-4n then n = 7
3n+18 = 39 -4n 3n+4n = 39 -18 7n = 21 n = 3
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
4n = 3n + 44n - 3n = 3n - 3n + 4n = 4check:4n = 3n + 44(4) =? 3(4) + 416 =? 12 + 416 = 16 True
3n + 4n = 42 7n = 42 n = 42/7 n = 6
3 + 3n = 9 + 2n + 4n n = -2
It is 12n2 + 3n - 58
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
Subtracting 3n from each side gives 12 = 4n or 4n = 12. n = 12/4 n = 3
