31/2x - 4 = -38 1/8

how do i do this?

Hello, I will try my best to explain this to you as simple as possible.

First, you have to pass the -4 to the other side, like this:

-3 1/2x - 4 = -38 1/8

              ↓

-3 1/2x = -38 1/8 - 4

Then, you have to subtract -4 from -38 1/8, like so:

-3 1/2x =  -38 1/8 - 4

              ↓

-3 1/2x = -42 1/8

My preferred method for this next step is this:

-3 1/2x = -42 1/8

              ↓

-7/2x = 337/8

Then, we divide:

-7/2x = -42 1/8

              ↓

x = (-337/8) / (-7/2)

x = 12.0357142857

So, the answer is: 12.0357142857.

Hope this helped! c:
