-3n+5n+4 = -4 2n = -4-4 2n = -8 n = -4

When n = 4, 3n = 3*4 = 12

3n -5 = 19 3n = 19+5 3n = 24 n = 8

-3n + 4 = 2Subtract 4 from each side ==> -3n = -2Divide each side by -3 ==> n = 2/3

4n - 7n = 21(4-7) n =21-3n = 21divide both sides by -3n = -7

3n-5=13 +5 +5 3n=18 /3 /3 n=6

3n x 3n = 9n if 9n = 36 then n = 36/9 = 4

21

N = 4

3n+6=18 n+2=6 n=4

In 3n-1 equals 11, n is 4.3n - 1 = 113n - 1 + 1 = 11 + 13n = 123n/3 = 12/3n = 4

The question seems ambigous, but I will consider n 2n to be solving for n:2n - 3n = n/3 + 14-n = n/3 + 14-3n = n + 42-4n = 42Thus, the solution is n = -42/4 = -21/2 = -10.5.
