John was asked to solve the following system using multiplication and addition. He tried twice to come up with an equivalent set of equations. Analyze each of John's attempts. Tell whether the attempt is an accurate and equivalent system of equations. Describe, in complete sentences, which operations were completed in each system and tell why or why not they were accurate operations.
Original System of Equations:
7x - 3y = 4
2x - 4y = 1
Attempt #1:
28x - 12y = 16
-6x + 12y = -3
Attempt #2:
14x - 6y = 4
-14x + 28y = 1
