I need help with the equation:

1/8x - 2/3 + 1/8x = 5/4x - 5/6

I need to refresh my brain...

Move X to one side of the equation and isolate it.

1/8x - 2/3 + 1/8x = 5/4x - 5/6

$\frac 18 x - \frac 23 + \frac 18 x = \frac 54 x - \frac 56$

Note that

$\frac 18 + \frac 18 = \frac 28 = \frac 14$

To simplify the right side of the equation:

$\frac 23 - \frac 56$

The common denominator is 6

$\frac 23 = \frac 46$

You'll have

$\frac 46 - \frac 56$

You take it from there.
