Question

You divide first what operation would you use last 18(d/3-9)=198

Answer 1

addition

Explanation:

18 ( d - 9 ) = 198

3

divide both side by 18

d - 9 = 198

3 18

d - 9 = 11

3

multiply both sides by 3

d - 27 = 33

add 27 to both sides

d = 33 + 27

lastly, add them together

d = 60

therefore, the last step is addition
