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

If n is 2, then 3n plus 1 would equal 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.

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

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

n=-9.6

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

That question has no answer since n must equal 3 and if you substitute n in 3n-2, you will see that it does not equal 3, it equals 7.

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