Plz ! i rlly need this question ! leeann created this solved this proof. she wants to know if she solved it correctly. after looking at the proof, decide whether she solved the proof correctly. if she did not explain why it is incorrect and correct it. given : 7y-84=2y+61 prove: y= 29 statements reasons 7y-84=2y+61 given 5y - 84 = 61 subtraction property of equality 5y = 145 subtraction property of equality y = 29 division property of equality

she is right that y = 29, but step three should be addition property of equality.

work: let's see how she worked to isolate y. she started by subtracting 2y from both sides, so so far she is correct. after that, she added 84 to both sides, and again that is a correct step, but her proof is wrong, since you are adding and not subtracting 84, it's the addition property of equality. lastly, she divided 145 by  and correctly got 29. so yes, she is correct.

1) is right
