Which system of equations is equivalent to the following system? 4x + y = 4
2x + 7y = 28

4x + y = 4
−2x − 7y = 28
4x + y = 4
−8x − 28y = 112
−28x − 7y = −28
2x + 7y = 28
−8x − 2y = 8
2x + 7y = 28

With these: 18/36 = 1/? missing number change 1 5/8 to improper fraction. change 19/5 to a mixed number.
