let x caught x fishes. y caught x/5 fishes.

x+x/5=36

6x/5=36

x= 36*5/6
x=30

x caught 30 fishes
y caught 6 fishes

It so simple

let the number of fish caught by x be 5y
5y+y=36

6y=36
y=6
y caught 6 fish out of 36

ok the easyest way to do this is remember the ratio between x and y which obviously is 5:1
now this means that y got 1 of every 6 fish court.
if 36 fish were court that means that y got 6 fish because 36/6=6

Let the total number of fish caught be 6a.

X caught 5a fishes.
Y caught a fishes.

6a=36
a= 36/6
= 6

Y = a
= 6

You have two equations - write the given information in numerical data. 1) x + y = 36 and 2) x = 5y

*Since the x-variable is isolated in the 2nd equation...

First:replace "5y" with "x" in the 1st equation...

5y + y = 36

*Combine "like" terms...

6y = 36

*solve for "y" by isolating it on one side > divide both sides by 6...

6y/6 = 36/6
y = 6

"Y" caught 6 fish.

X+Y=36
5Y=X

So Y=X/5
and X=36-Y

So Y=(36-Y)/5
then 5Y=36-Y
Y=36/6=6
Y caught 6 fish

x + 5x = 36
6x = 36
x = 36/6
x = 6

Y caught 6; x caught 30...5 times 6

total fish caught=36
X caught 5 times as many as Y.
therefore X=5Y
according to question,
X+Y=36
substitute value of Xfrom above
equation becomes
5Y+Y=36
6Y=36
Y=6
THEREFORE NUMBER OF FISH CAUGHT BY Y ARE 6.

let the number of fishes Y caught be A.
Therefore, X caught 5A fishes.

6A = 36
A = 6

Hence, Y caught 6 fishes

1/2 of 36 is 18. 18x5=90. 90 is the answer
