Madison 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 : 4 (5n + 7) - 3n = 3 (4n - 9) Prove: n=-11
Statements Reasons
4 (5n + 7) - 3n = 3 (4n - 9) Given
20n + 28 - 3n = 12n - 27 Distributive Property
17n + 28 = 12n - 27
Simplify
5n + 28 = - 27 Addition Property of Equality
5n = - 55 Multiplication Property of Equality
n = - 11 Division Property of Equality
