Can someone please help with the below problem? The correct answer is E; please clarify as well. I might not be reading is correctly.
If E is correct, then that must mean that -4t = 32t = 8. I'm confused ??
Thank you!!

Work out the answer choices by doing simple algebra and see which one's incorrect:
A.) 7x-5=9--> 7x=14--> x=2 No.
B.)p-3p+15=10--> -2p=-5--> p=2.5 No
C.) 7y=28--> y=4 No.
D.) 8w=64--> w=8 No.
E.) -4t=32--> t=-8. The question says that t=8, so this is our answer.
A.) 7x-5=9--> 7x=14--> x=2 No.
B.)p-3p+15=10--> -2p=-5--> p=2.5 No
C.) 7y=28--> y=4 No.
D.) 8w=64--> w=8 No.
E.) -4t=32--> t=-8. The question says that t=8, so this is our answer.
