3n+1=7 3*2+1=7
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
3n + 6 = n + 202n = 14n = 7
n=-9.6
3n + 4n = -14 7n /7 = -14 /7 n = -2
5n + 7 = 28 + 2n (-2n) 3n + 7 = 28 (-7) 3n = 21 therefore, n = 7
3n+1=7 3*2+1=7
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
3n + 6 = n + 202n = 14n = 7
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
4n
n=-9.6
3n + 4n = -14 7n /7 = -14 /7 n = -2
n = -6
No. 3n is not a factor of 3n + 7.
3n+3=n+7 3n+3-n=n+7-n (subtract n from both sides) 2n+3=7 2n+3-3=7-3 (subtract 3 from both sides ) 2n=4 2n/2=4/2 (divided by 2 on both the sides) n=2 Answer: n=2
n = 7. 3(7) + 7 = 28. 21+7=28
