Answer:
hours
Step-by-step explanation:
Let x be the time ( in hours ) you feel good and y be the time ( in hours ) that you get tired.
As per given , we have
x+y= 8
Since : 
So , we have
20x+12y=122
According to the given question , we have the following system of equations ,

Multiply 12 on both sides of equation (1) , we get

Eliminate equation (3) from (2) , we get

Hence, you felt
hours good.
Answer:
w = .5
Step-by-step explanation:
-4w + 18w+2=10 -6w

14w + 2w = 8 - 2w + 2w
16w = 8
16w/16 = 8/16
w = .5
