3n+1=7 3*2+1=7

3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1

3n + 7 = 163n + 7 - 7 = 16 - 73n + 7 - 7 = 16 - 73n = 16 - 73n = 93n/3 = 9/33n/3 = 9/3n = 9/3n = 3Check:3 x 3 + 7 =? 169 + 7 =? 1616 =? 16n=3 is the correct answer.

3n + 6 = n + 202n = 14n = 7

n = 7. 3(7) + 7 = 28. 21+7=28

3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7

4n

n=-9.6

6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n

5n + 7 = 28 + 2n (-2n) 3n + 7 = 28 (-7) 3n = 21 therefore, n = 7

3n + 4n = -14 7n /7 = -14 /7 n = -2

No. 3n is not a factor of 3n + 7.
