Answer:
64.94
Explanation
You arrange the numbers in such a way, to be in line with their decimal points like this:
70.7
-5.76
Then you subtract. Notice that on top of the 6 is nothing which is equal to 0
You would distribute -4(3 - 5x) into looking like:
-12 +20x
This gives you
-12 + 20x ≥ -6x + 9
