I'm trying to solve these equations but it seems I didn't get the correct one. please help if you still can.

Question

to solve the equations:

1. 0.4 =32z
2. 8n - 2 = 14
3. 2 (x + 3) = 4

Thanks a lot.

Answer 1

1.
0.4 =32z
0.4/32 = z
0.125 = z

2.
8n - 2 = 14
8n = 16
n = 2

3.
2 (x + 3) = 4
2x + 6 = 4
2x = -2
x = -1

Answer 2

Now, I understand, thank you,thank you very much, Ms. Sue.

Answer 3
