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

3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1

6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n

(7n - 4)(n + 3)

3n and n = 4? 3n ( the four replaces the n 3(4) = 12 =======

7n - 2 + 3n + 4 = 7n + 3n - 2 + 4 = 10n + 2 which can be simplified to 2(5n +1)

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

N = 4

3n + 4 = 7(- 4 from both sides)3n = 3(divide both sides by 3)n = 1

The answer to -2(4+3n)=24 is:-5.33

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

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

3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (3n + 3 - 3n + 1) = 3n + 2 + (4) = 3n + 6

6n - 4 - 3 = 3n + 10 + 4n -7 = 7n - 6n + 10 -17 = n

(7n - 4)(n + 3)

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

(3n-2)/8 = (n+4)/55(3n - 2) = (n+4)815n - 10 = 8n + 327n = 42n = 6
