It depends on what level of classes you take, but algebra classes in college do tend to be harder than algebra classes in high school or middle school.
If we write 
where we see 
in the equation and set the result equal to 
, we get the result.
2(8-4)^2-5
16-32-5
-21
you can change the -10/2 to a -5 and it will be easier.
The answer is 6hours in 122 minutes do umknow
I believe this would be 5x/2x-5
Hope this helps!
