Respuesta :
In order to isolate y you would first subtract 20x from the left side and move it to the the right side.
1. -4y=-20x - 28
Then divide every number in the equation by 4 to isolate y once again.
2. Y= 5x + 7
Since negatives are being divided by negatives they become positive
Hope I helped’
