C. The first is a solution, but the second is not.
5x - y/3 = 13 ; (2,-9)
substitute the letters:
5(2) - (-9/3) = 13
10 - (-3) = 13 : note that deducting a number with a negative sign turns both sign as positive.
10 + 3 = 13 ;
13 = 13
5x - y/3 = 13 ; (3,-6)
5(3) - (-6/3) = 13
15 - (-2) = 13
15 + 2 = 13
17 = 13 not equal. not a solution

Answer:
$2.20
Step-by-step explanation:
Original price (before discount and before tax): $5
Discount is 60%.
Amount of discount is: 60% of $5 = 0.6 × $5 = $3
Price after 60% discount: $5 - $3 = $2
Tax is 10%.
Amount of tax is: 10% of $2 = 0.1 × $2 = $0.20
Final price = price after discount + tax = $2.00 + $0.20 = $2.20
