Step-by-step explanation:
first, we have to solve both sides.
-20 - (-20) = -20 + 20 since when you subtract a negative number, you are basically adding the positive form of that number.
so, the sum of a number and its additive inverse is always 0. and -20 and 20 are each other's additive inverses
so, the first part is 0
20 - (+65) = 20 - 65 since when you subtract a positive number, you are basically subtracting that number
so, the difference between a smaller positive and greater negative number is always negative.
so, we can write it like so: 20 - 65 = -65 + 20 = -45
0 and -45 are not equal, and a negative number is always smaller than 0, so the sign we will use is >
