For the sum we have the following properties:
The properties are commutative, asosiative, distributive and neutral element.
Commutative property: When two numbers are added, the result is the same regardless of the order of the addends.
Associative property: When three or more numbers are added, the result is the same regardless of the order in which the addends are added.
Neutral element: The sum of any number and zero is equal to the original number.
Distributive property: The sum of two numbers multiplied by a third number is equal to the sum of each summand multiplied by the third number.<span><span>
</span><span>For subtraction we have:
</span><span> The arithmetic operation of the subtraction (subtraction) is indicated by the minus sign (-) and is the opposite, or inverse, operation of the addition. </span><span>That is, it is an arithmetic operation that serves to find the difference between two numbers.
</span><span>
In subtraction A - B = D
</span><span>A is the minuendo
</span><span>B is the substraendo
</span><span>D is the difference
</span><span>Answer:
</span><span>The properties of addition and subtraction serve to rewrite and simplify calculations.</span></span>
The answer should be “D 60”

Answer:
<u>(3, -1)</u>
Step-by-step explanation:
<u>Given</u>
<u>Subbing the value of y</u>
- 4x + 5(3x - 10) = 7
- 4x + 15x - 50 = 7
- 19x = 57
- x = 3
- y = 3(3) - 10
- y = 9 - 10
- y = -1
- Solution is <u>(3, -1)</u>
