Answer:
10 pounds
Step-by-step explanation:
You forgot the inequality sing, but since Antoine can't spend more than $18.20, I am positive that the sign is
(Antony can spend $18.20 or less than $18.20).
Therefore, our inequality is: 
where
is the pounds of oranges
Let's solve step-by-step to find how many pounds of oranges he can buy
Step 1. Subtract 5.20 fro both sides of the inequality


Step 2. Divide both sides of the inequality by 1.30


We can conclude that Antony can buy 10 pounds of oranges.

The answer for 9/4 is 2.25
Answer: In general, a solution of a system in two variables is an ordered pair that makes BOTH equations true. In other words, it is where the two graphs intersect, what they have in common. So if an ordered pair is a solution to one equation, but not the other, then it is NOT a solution to the system
