Answer:
80 boxes of noodles
Step-by-step explanation:
10 cases x 8 boxes in each case = 80 boxes of noodles
10 x 8 = 80
He should have added 1 to both sides to make the -1 on the right go to 0.
Then it would be 0 + m = -16 + 1 = -15
You can check your work by adding -1 and -15, which does in fact equal -16.
Hope this helped :)
