Question

Ok I'm having a hard time finding the right one, I keep second guessing myself so please help?
The steps in the simplification of the expression 6 + 3x + 4y − 2x – y − 7 are shown below.

Step 1: 6 – 7 + 3x − 2x + 4y − y
Step 2: (6 − 7) + (3x − 2x) + (4y − y)
Step 3: −1 + x (3 − 2) + y (4 − 1)
Step 4: −1 + x (1) + y (3)
Step 5: −1 + x + 3y

Which statement is correct?

Step 2 uses associative property of addition, and step 3 uses distributive property of addition.

Step 1 uses commutative property of addition, and step 5 uses associative property of addition.
Step 4 uses associative property of addition, and step 3 uses commutative property of addition.

Step 2 uses distributive property of addition, and step 4 uses commutative property of addition.

Answer 1

would it be the last one? 0.0

Answer 2

A

Answer 3

do you know why?

Answer 4

i was just about to ask why...

Answer 5

please explain how you got A...cause I thought it might be D...

Answer 6

Associative Property of Multiplication
For real numbers a, b, and c, a • (b • c) = (a • b) • c.

Answer 7

Distributive Property
For real numbers a, b, and c, a(b + c) = ab + ac.
