Please, present no more than one or two problems at a time. Nine or ten problems are visible on your worksheet; it's possible that that was a turn-off for potential helpers.
Problem #4: You are to solve "x/7=3." Your choices are {20, 21, 22}.
One way would be to divide each of the three possible answers {20, 21, 22} by 7. Does 7 divide into any of them without a remainder other than zero (0)? If so, that x-value is your answer. An alternative approach would be to multiply 7 by 3. Does your result equal any of the possible answers {20, 21, 22}?
