Answer:
Your missing number is -87.5.
Explanation:
You want to follow reverse order of operations to isolate your variable x
First, you plug in y= 700 to get::
700 = (24x)/7 +1000
Then subtract 1000 from both sides to get:
-300 = (24x)/7
Then multiply both sides by 7 to get:
-2100 = 24x
Then, divide by 24 to get:
-87.5 = x
Thus, your answer x= -87.5
