Question

a) 2n+3=8*2 b)3n-2=3n:9 c)8n=2 3n

Answer 1

2n+3=16
2n=16-3
2n=13
n=13/2

3n-2=3n/9
3n-2=n/3
n=3(3n-2)
n=9n-6
9n-n=6
8n=6
n=6/8=3/4

8n=6n
8n-6n=0
n=0

Answer 2

a) 2n+3=16
    2n=16-3
    2n=13
     n=13 supra 2
b) 3n-2=3n supr 9
     3n-2=b pe3
     9n-6=n
     9n-n=6
      8n=6
       n=6 pe 8
       n=3 pe 4
c)8n-6n=0
    2n=0
     n=0
