Answer: The first one, (Divide the second equation, 2x + 4y= 32, by 2.)
Step-by-step explanation:
Answer: No, it does not matter.
Step-by-step explanation:
In addition the order does not matter, this is because of the commutative property of the addition, that says that: A + B = B + A
and the associative property, that says that:
A + (B + C) = (A + B) + C
for example, if you have 4 chips and your friend gives you her 5 chips, now you have a total of 4 + 5 = 9 chips.
The case is the same if you have 5 chips and your friend gives you 4 chips, now you have 5 + 4 = 9 chips.
Other example is that:
5 chips + ( 2chips + 1 chip) = 5 chips + 3 chips = 8 chips
(5 chips + 2 chips) + 1 chip = 7 chips + 1 chip = 8 chips
You can see that the order does not matter.

Answer:
Doubling the actual answer and increasing it by 2.
Step-by-step explanation:
The calculator is returning 26, instead of 12. Note that 26 is 2 more than twice of 12.
i.e.
26 = 2(12) + 2
Calculator is returning 32 instead of 15. Here again we can note the same logic. 32 is 2 more than twice of 15.
i.e.
32 = 2(15) + 2
Calculator returns 202 instead of 100. Here again the same logic holds true.
i.e.
202 = 2(100) + 2
So, what the calculator is doing is:
Doubling the actual result and increasing it by 2.
