Answer:
12
Step-by-step explanation:
if you multiply everything by 5, then you can get rid of the fraction and the equation would now look like this:
x - 40 = 20
and now you can answer this simply
x - 40 = 20
+40 +40
x = 60
and since you multiplied 5 beforehand, now you have to divide by 5 to get the real answer
60 ÷ 5 = 12
therefore, x = 12
I think it is -0.125.
It might also be 0.125
For this case we have, by definition:

So, we have:

On the other hand we have that by definition:

Thus, the expression can be written as:




So, we have:
