Answer:
Part A: You are buying candy bars online. They cost $6 each and there is an $18 shipping fee. You have $72 to spend. How many candy bars can you get?
Part B: x=9
Explanation:
6x + 18= 72
You want to get x alone:
Subtract 18 from both sides
Rewrite:
6x= 72-18
Now, subtract 72-18
Rewrite:
6x= 54
Divide 6 from both sides
So, that would be 54/6
Answer: x=9
Hope this helps!!
