There are 40 cats in the ecosystem.
You set 1/5 equal to x/200. Then you cross multiply the fractions to get 5x=200. You divide both terms by 5 to get x, which equals 40.
First of all why is there 2 similar equation connected to one another?
Second in order to solve this all you need to do is plug in the number and solve for x
For 485
85x+60=485
85x=420
X=5
Do the same thing and you get 3
Y X
80 32
100 x'
80x' = 100*32
80x' = 3200
x' = 3200/80
x' = 320/8
x' = 40
