Question

can someone explain this to me.

Given the equation 7x + 2 = 2 + 5x – 6, use the commutative property to rearrange the terms so that like terms are next to one another. This gives the equation 7x + 2 = 2 – 6 + 5x. Then use the ____________________ to group the like terms. This gives the equation 7x + 2 = (2 – 6) + 5x. Next, combine like terms to get the equation 7x + 2 = –4 + 5x. Use Use the subtraction property of equality to subtract 5x from both sides of the equation. i think its the associative property of addition am i correct?

Answer 1

so you need to find what kind of property it is?

Answer 2

yeah i do

Answer 3

Commuutative property:In mathematics an operation is commutative if changing the order of the operation does not change the end result.

Answer 4

is that what you need?

Answer 5

oh so just that?

Answer 6

the question only wants to know the property so yeah thats all it wants.

Answer 7

well if the question is asking what property it is then yes you can write it like this if your teacher is strict

7x + 2 = 2 – 6 + 5x=commutative property

Answer 8

o ok :D

Answer 9

thanks :D

Answer 10

anytime!
