Answer:
D) 111
Step-by-step explanation:
(-75) - (-20) +x = 56
A negative minus a negative means add
-75 + 20 +x =56
-55 +x = 56
Add 55 to both sides
-55+55 +x = 56+55
x = 111
Answer:
Two negatives make a positive.
-75 - (-20) = -75 + 20
Do the math now:
-75 + 20 = -55
Write down the final equation to get the answer, which is finding the difference between 56 and -55:
Two negatives again...they make a positive, so re-write the equation:
56 - (-55) = 56 + 55
Get the answer by solving:
56 + 55 = 111
