Answer :
Follow PEMDAS in reverse. So you would start off undoing the +7. Which means you subtract 7 from both sides
Then undo the -2 multiplying with the b. So you divide both sides by -2
The final answer is therefore D) subtract 7 and then divide by -2
Then undo the -2 multiplying with the b. So you divide both sides by -2
