Question

Fred weighs 40 pounds less than twice Barney. Their combined weight is 320 pounds. Let F = Fred's weight in pounds and B = Barney's weight in pounds. Write a system to represent the situation. DO NOT SOLVE.

Answer 1

Explanation:

Using the information provided we can create two different equations for this system. The first of which would be Fred's overall weight, while the second equation would be Fred's and Barney's combined weight. These equations would be the following...

F = 2B - 40

320 = F + B

As requested I will not solve the system of equations and leave them as they are.
