Answer 1

You have submitted quite a few questions and not worked any of the parts. Tutors are not here to do your homework assignments. Tutors are to help you learn to do them yourself. If you cannot even start the problems, then you need tutoring sessions, not answers to these questions.

Here is the answer to the 1st one"

7(n+10)=98

Divide equation by 7

n+10=14

Subtract 10 from each side

n=4
