Question

If `5(y+10)=40`, what is the value of `1/4y`?

Answer 1

`1/4y=y/4=-1/2`

Explanation:

To find `1/4y=y/4` means you have to find the value of `y` then divide it by `4`. This is if you wrote the question correctly because `1/4y !=(1)/(4y)`. I am pointing this out because I just noticed that if you don't put parentheses, you are writing something different than if you put them on the numerator AND denominator.
I am going to work with what I see.

`5(y+10)=40`

`5y+50=40`

`5y=40-50`

`5y=-10=>y=-10/5=-2`

`y=-2`

`=>y/4=-2/4=-1/2`

I hope this is helpful :)
