The largest fish ever caught in Lake A weighed 650 pounds. This is 208.2 pounds less than seven times the weight of the largest
Anika [276]

Answer:

122.6 pounds

Step-by-step explanation:

Let's call the weight of the largest fish from lake A 'x', and the weight of the largest fish from lake B 'y'.

If x is 208.2 pounds less than seven times y, we have that:

x = 7y - 208.2

We know that x is equal 650 pounds, so we can find y:

650 = 7y - 208.2

7y = 650 + 208.2

7y = 858.2

y = 122.6\ pounds

So the weight of the largest fish caught in Lake B is 122.6 pounds
