Final answer:
The equation to find out how much money Adam has raised is 3x + 14 = 56. After solving this equation, we find that Adam has raised $14.
Step-by-step explanation:
To find out how much money Adam has raised, we need to set up an equation based on the information given. We are told that Arlene has raised $56 which is $14 more than three times the amount Adam has raised. Let's represent the amount Adam has raised as x.
The translation of the given information into an equation will look like this:
3x + 14 = 56.
To solve for x, we subtract 14 from both sides to get 3x = 42. Then, we divide both sides by 3 to find x, which represents the amount raised by Adam:
x = 14.
So, the equation you could use to find out how much money Adam has raised is 3x + 14 = 56.
