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

If n is 2 3n plus 1 equals 7?
If n is 2, then 3n plus 1 would equal 7.
What is 3n plus 4 equals 7?
3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
3n plus 7 equals 16 means?
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.
What is 3n plus 7 equals 28?
n = 7. 3(7) + 7 = 28. 21+7=28
3n plus 6 equals n plus 20?
3n + 6 = n + 202n = 14n = 7
If n is 2 3n plus 1 equals 7?
If n is 2, then 3n plus 1 would equal 7.

3n + 6 = n + 202n = 14n = 7
What is 3n plus 2n equals 7 plus 4n?
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
What is the solution to 6n-4-3 equals 3n plus 10 plus 4n?
6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n
What is the answer to 5n-7 equals 3n plus 2?
4n
What is 2n plus 3n plus 7 equals -41?
n=-9.6
What is the sum of the equation 3n plus 4n equals -14?
3n + 4n = -14 7n /7 = -14 /7 n = -2
What is 3n-2 equals n equals 3?
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.
What is the answers for this problem 3n-7 plus 2n equals 8n plus 11?
n = -6
