Let's let j represent the amount Jim has.
Then we can write the following expressions to replace the text for Anthony, " Anthony has 25 less than twice Jim's amount": 2j - 25
Then we can create an equation using the information that states that Anthiny has 75: 2j - 25 = 75
We can solve this equation using inverses operations:
2j - 25 = 75
2j - 25 + 25 = 75 + 25
2j = 100
2j/2 = 100/2
j = 50
Therefore Jim has 50 and Anthony has 75.
