Hi. I've tried doing these problems and got long decimals that don't make sense. Please help!!

1) 13x + 6=4x-4
2) (1/2)x + 8= 3x + 2
3) (n/3) + 8=n + 1
4) 2n + 3= 2n + 3 I don't know how I would find n in this one!!
5) 5x + 2(2x-1)=-16
Thanks so much for all the help!!!

1) 13x + 6=4x-4
13x- 4x = -6 + (-4)
9x = -10
x = -1.111

4) If you copied the problem correctly, it can't be solved.

5) 5x + 2(2x-1)=-16
5x + 4x - 2 = -16
9x = -14
x = -14/9
x = -1.5556
Can anyone else help with the problems? Much appreciated :)
