Answer:
Associative Property
Commutative Property
Distributive Property
Identity Property
Step-by-step EXPLANATION
ASSOCIATIVE PROPERTY
In this property, irrespective of the regrouping between a number and the addent within a bracket, the sum, value does not change.
For example:
(A + B) + C = A + ( B + C)
COMMUTATIVE PROPERTY
In commutative Property, you will always get thesame results after changing the order or position of the addent.
For example:
A + B = A + B
Also,
A + B = B + A
DISTRIBUTIVE PROPERTY
Basically here, please note that, the sum (addition) of two numbers times a Third one is always equal to the sum of these numbers times the third one.
For Example:
A x (B + C) = AB + AC
IDENTITY PROPERTY
This property is the easiest of all, it simply says that "Add a number to Zero must always be that number".
For example:
A + 0 = A
B + 0 = B
C + 0 = C

2x-5y=16 =>10x-25y=80
5x+3y=9 => 10x+6y=18
subtract one from the other: (6-(-25)y=(18-80), 31y=-62, y=-2
plug y=-2 in 2x-5y=16 to find x: 2x+10=16, x=3
12x+y=12*3-2=34

Step-by-step explanation:
Using BODMAS : brackets, division, multiplication, addition
Answer:
Both calculated the slope as 1/3
Step-by-step explanation:
Avis:
Rise = 4
Run = 12
Rise goes over the run: 4/12
4/12 simplifies into 1/3
Alec:
Rise= 2
Run= 6
Rise goes over the run: 2/6
2/6 simplifies into 1/3
