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.
3n + 4n = 42 7n = 42 n = 42/7 n = 6
How do you find the answer to this equation: 3n equals 18
3n = 0.138 n = 0.046
3n+5=2n+7 subtract 2n on both sides. n+5=7 subtract 5 to the other side. n=2 the answer to n is 2. Hoped that helped. (:
3n+1=7 3*2+1=7
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1
4n
3n + 4n = -14 7n /7 = -14 /7 n = -2
3n + 6 = n + 202n = 14n = 7

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=-9.6
4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7
No. 3n is not a factor of 3n + 7.
3n + 4n = 42 7n = 42 n = 42/7 n = 6
