Answer:
y= 4
Step-by-step explanation:
Okay so this is inverse operations.
You have to move the 2y over underneath the 6y and subtract them, you should get 4y. Your problem should now look like this. 4y-20=-4
Now you need to more the +20 over underneath the -4 and add them. Your problem should now look like this. 4y= 16
You now divide 4 into 16 which will give you 4
So y= 4
Have a good day!
Its the last option they both are as far from 0 on the number line
Hope this helps and good luck on ur guyss exams :)
