Question 16
Given that two golfers completed one round of golf.
It is stated that the first golfer had a score of +6 and the second golfer had a score of -3.
- Let suppose 'x' be the number of shots the first golfer took.
It is clear that the first golfer is 6 over par, while the second golfer is under 3.
Thus, the equation becomes:

adding -3 to both sides

simplify

Thus, the second golfer has taken 9 more shorts.
Question 17
When we talk about credit, it means:
Credit = +
When we talk about debt, it means:
Debit = -
Thus,
Credit = +84
Debt = -29
Balance = 84 + (-29)
= 84 - 29
= 55
Thus, the balance is: 55
