Let a = cost of an apple and p = cost of a peach
From the two statements we can create the following system of equations:
2a + 3p = 1.65
3a + 2p = 1.60
Since we want to know the cost of a peach, let's eliminate the "a" terms by creating opposites. The LCM for 2 and 3 is 6 so I will multiply the top equation by 3 and the bottom equation by -2. This will create opposites to cancel "a" terms.
3(2a + 3p = 1.65) → 6a + 9p = 4.95
-2(3a + 2p = 1.60) → -6a - 4p = -3.20
The result of adding → 5p = 1.75
The result of ÷ 5 → p = .35
This means one peach cost .35 or 35 cents

Answer:
An equation could be 2-4= -2
Step-by-step explanation:
You would count down 4 times from the the number 2 (below the line that says 3) then your answer would be -2 since below it, is -3. Obviously the number obove it would be 2.
