You seem to be saying that Y=4/X+SQRT X +0.2 -5X, and that x is given as 4/5. To evaluate <span>Y=4/X+SQRT X +0.2 -5X, replace each occurrence of x with 4/5:
y = 4 / (4/5) + sqrt(4/5) + 0.2 - 5(4/5)
= 5 + 2 / sqrt(5) + 0.2 - 4
Can you simplify this further?

A) x * y = 196A) x = 196 / y
B) x + y = 35Substituting A) into B)
B) 196 / y + y = 35Multiplying both sides by y
B) 196 + y^2 = 35yB) y^2 -35y + 196 = 0
X1 = 28X2 = 7
Answer:
57x = 1311
x = 23 hours
Step-by-step explanation:
I don't know how you would model this with two equations but the answer is 23 hours.
