Question

70x + 25 = 50x +75
How many hours of service do the services cost the same?

Answer 1

2.5 hours

Explanation:

70x+25=50x+75

step 1 subtract 25 from each side

25-25 cancels out

75-25=50

Now we have

70x=50x+75

step 2 subtract 50 from each side

70x-50x=20x

50x-50x cancels out

now we have

20x=50

step 3 divide each side by 20

20/20 cancels out

50/20=5/2 or 2.5

so we can conclude that it will take 2.5 hours of service for the services to cost the same
