Step-by-step explanation:
(fx+cd)/(x-f)=1/2
Cross multiplication,
2*(fx + cd) = 1 * (x-f)
2fx + 2cd = x - f
2fx - x = -2cd - f
x (2f - 1) = -2cd -f
x = (-2cd-f )/ (2f-1)

Answer:
74 weeks
Step-by-step explanation:
Given :
Let x = number of weeks
Gallon A:
Capacity = 666
Leak rate = 4 gallons per week
666 - 4x
Gallon B:
Capacity = 888
Leak rate = 7 gallons per week
888 - 7x
666- 4x = 888 - 7x
666 - 888 = - 7x + 4x
-222 = - 3x
x = 222 / 3
x = 74
After 74 weeks
Your answer is 38.5. Dont forget to add units if there is any
