-3x = -3 because you would multiply one of the equations by -1 to eliminate y.

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!
This is most likely an example of correlation rather than causation. It may seem like the cat is staying indoors because of the rise of apples growing in the backyard, but it cannot be proven that one directly causes the other.
