Q2.1 Please provide justified answer asap for all parts

Give an example of an addition problem with three addends that would be much easier to solve (mentally) by using the commutative property of addition.

You were asked to identify the property that justifies the following statement, if it is true: −7x+25/3y2−z=1/3y2−z⇔−7x+8y2=0 Are these quantities equal? If so, choose which property justifies the statement, and enter the appropriate quantity in the box below. If not, consider a multiplicative relationship, or the possibility that the statement is false. Selecting an option will display any text boxes needed to complete your answer.
