Question

I’m so confused what does N equal?

Answer 1

N = 1 or 2n = 2

8n -3n + 12 = 3n + 14
5n + 12 = 3n + 14
2n = 2
N = 2

Answer 2

Solving 8n-3(n-4)
             =8n-3n+12   (multiply -3 to n and -4)
             =5n+12
we got 14+3n=5n+12

now subtract 5n to both sides
3n-5n=-2n  and   on the right side cross out 5n from the right side because 5n-5n=0

we got 14+-2n=-12

subtract 14 to both sides   ( cross out 14 from the left side and subtract it to -12

we got -2n=-26

divide -2 to both sides 

so the answer =13
