3 + 3n = 9 + 2n + 4n n = -2
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
4n -14 = 22 4n = 22+14 4n = 36 n = 9
4/9 = 20/n 4n = 9(20) 4n = 180 n = 45

3 + 3n = 9 + 2n + 4n n = -2
6n -3=2n+9 6n-2n=9+3 4n=12 n=12/4 n=3
3n - 9 + 4n = 8nCombine like terms:7n - 9 = 8nSubtract 7n from both sides:-9 = n
n = 1 7n + 6n - 5 = 4n + 4 13n - 5 = 4n + 4 13n - 4n - 5 = 4n - 4n + 4 9n - 5 = 4 9n -5 + 5 = 4 + 5 9n = 9 n = 1
4n -14 = 22 4n = 22+14 4n = 36 n = 9
No! It equals 15, but 9-6=3.
