4-9 is -5
The total expenses of Marco's account are $174. The ending balance is $81. So, the starting balance will be $255.
Option A is correct for starting balance.
Further Explanation on Starting and Ending Balance
Given that Marco’s bank statement says that he has an ending balance of $81. The expenses $ of Marco is given as,
- T-shirt 20
- Gas 22
- Movie 13
- Video game 39
- Jeans 34
- Hat 15
- Books 31
The total expenses can be calculated as given below.
Total Expenses = Sum of all Expenses
Total Expenses = 20+22+13+39+34+15+31
Total Expenses = $174
The starting balance can be calculated as given below.
Starting Balance = 
Starting Balance = $ 255.

Answer:
(3, 2), (2, 3)
Step-by-step explanation:
x + y = 5
xy = 6
Solve the first equation for x.
x = 5 - y
Substitute 5 - y for x in the second equation.
xy = 6
(5 - y)y = 6
5y - y² = 6
y² - 5y + 6 = 0
Factor.
(y - 2)(y - 3) = 0
y - 2 = 0 or y - 3 = 0
y = 2 or y = 3
Now substitute 2 for y in the first equation and solve for x.
x + y = 5
x + 2 = 5
x = 3
One solution is x = 3; y = 2, or (3, 2).
Now substitute 3 for y in the first equation and solve for x.
x + y = 5
x + 3 = 5
x = 2
Another solution is x = 2; y = 3, or (3, 2).
Answer: (3, 2), (2, 3)
