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

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

Thanks a lot.

    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

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