Okay so let’s say the permit fish is the variable p.
The tarpon is 11p.
So, to set up the equation,
(11p)+p=168
Start by combining like terms on the left
12p=168
Divide both sides by 12 to isolate p
p=14
So therefore, the permit fish was 14 pounds.
To find the weight of the tarpon, insert the 14 back into (11p) 11(14)=154.
You can check by adding these together 14+154=168
So:
The permit fish weighed 14 pounds.
The tarpon weighed 154 pounds.
Hope this helps!
