Question

4.) Mr. Rod N. Reel caught a fish that weighed 3 pounds more than twice what fish that Mr. Mac Arille caught. If the sum of the welghts of the fish was 42 pounds, how much did each fish weigh?Expression for Mr. Mac's fish:Expression for Red's fish:

Answer 1

Mr. Mac's fish weighed 13 pounds.

Mr Rod's fish weighed 29 pounds.

Step-by-step explanation:

Let the weight of the fish caught by Mr Mac = x

The expression for Mac's fish: x

3 pounds more than twice what fish that Mr. Mac Arille caught = 2x+3

Therefore:

The expression for Rod's fish: 2x+3

The sum of the weights of the fish was 42 pounds, therefore:

`x+(2x+3)=42`

We solve for x.

`\begin{gathered} 3x=42-3 \\ 3x=39 \\ x=(39)/(3) \\ x=13\text{ pounds} \end{gathered}`

0. Mr. Mac's fish weighed 13 pounds.

1. Mr Rod's fish weighed 42-13 = 29 pounds.
