15-3n=n-1
3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6
4n-8=3n+2 4n=3n+2+8 4n=3n+10 4n-3n+10 n=10 N = 10
3n + 2n = 7 + 4n 5n = 7 + 4n 5n - 4n = 7 n = 7
n=1/3 or 0.333333333333333 repeated.
3n = 15 + 12 = 27, 27/3 = 9 = n
n=6
15-3n=n-1
3n + 6 = -9 Subtract 6 from both sides: 3n = -15 Divide both sides by 3: n = -5 Therefore n = -5
3n + 6 = n + 202n = 14n = 7
3 + 3n = 9 + 2n + 4n n = -2
n=-9.6
10n+2
4n + 3y
4n
7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)
3n+6=18 n+2=6 n=4
