Answer:

x = 3/10

Step-by-step explanation:

−1/2 − (−4/5) = x

First, switch sides.

x = −1/2 − (−4/5)

You are subtracting a negative number. Subtracting a negative number means add a positive number.

x = -1/2 + 4/5

Now you are adding two fractions, so you need a common denominator. The LCD of 2 and 5 is 10.

x = -5/10 + 8/10

x = 3/10
