Answer 7

The Order of Operations is:
Parentheses

Your problem is 7x[8+(16-9)]/5
According to the Order of Operstions, we start with the innermost parentheses, which would be 16-9. 16-9=7
Our new equation looks like this: 7x[8+7]/5
We still have a pair of parentheses, so we solve that next. [8+7}=15.
Our new equation looks like this: 7x15/5.
According to the Order of Operations, we now multiply 7x15=105
Our new eqution looks like this:105/5
105/5=21, so that is our answer.
