You solve the equation by manipulating it until you have only "x" on one side.
12/8 = (x/40) - x
So we can multiply both sides by 40 to get rid of the x/40:
12/8 * 40 = x - 40x
60 = -39x
x = 60/-39
x = -1.538 (to 3 decimal places only)
IF you actually meant (and this is why it is important to write our questions as accurately as possible else mathematicians will assume you are using the agreed conventions):
12/8 = x/(40 - x) then
x = 12/8 * (40 - x)
x = 60 - 1.5x
2.5x = 60
x = 24
