2/8 = 5/y...2 roosters to 8 chickens = 5 roosters to y chickens
cross multiply because this is a proportion
(2)(y) = (8)(5)
2y = 40
y = 40/2
y = 20....so with 5 roosters comes 20 chickens
2/8 reduces to 1/4....so with 1 rooster comes 4 chickens
ur table :
roosters : 2.....1......5
chickens: 8.... 4.....20

Answer:
x ∈ {-0.465, 1.014}
Step-by-step explanation:
The equation can be cast in the form f(x) = 0, and solved easily using a graphing calculator. That shows x ≈ -0.465 and x ≈ 1.014. The same calculator can iterate the roots to full calculator precision.

The equation can be made a quadratic by the substitution ...
z = e^(2x)
Then we have ...
