need help before 6:30pm i have to show my work

Answer:
1. y=-5x-4
2. y=-3/2x+2
3. y=-12x+8
Step-by-step explanation:
1. subtract 5x from both sides to get y=-5x-4
2. subtract 9x from both sides to get 6y=-9x+12. Then divide everything by 6 to get y=-3/2x+2
3. subtract 3x from both sides to get 1/4y=-3x+2. Then divide everything by 1/4 to get y=-12x+8
I hope that this helps!
