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.

		Addition Property of Equality

anonymous · Answer

i think it is equality one but idk

anonymous · Answer

what a weird question
i think they are looking for "associative"

radar · Answer

7x-5x=-6
x(7-5)=-6
2x=-6
x=-3

I'm not sure of the objective of this exercise.

anonymous · Answer

compare 
$$7x + 2 = 2 – 6 + 5x$$ with 
$$7x + 2 = (2 – 6) + 5x$$ and we see that the only difference is the introduction of parentheses
associative law says $(a+b)+c=a+(b+c)$  but the first expression contains no parentheses, so it is a bit confusing

anonymous · Answer

ya i did the math but was not sure what 'property' they were

anonymous · Answer

associative law says parentheses are not necessary, so i think that is what the author of this rather idiosyncratic question is looking for
