One number is seven more than three times another number. If the sum of the numbers is 15, find the numbers.

2 and 13

Step-by-step explanation:

We can use systems of equations here to find both the numbers. Let's assume one of the numbers is and the other is .

We know that these numbers add up to 15, so .

We also know that one of these numbers is 7 more than 3 times the other, so .

We can now substitute the equation into .

Combine like terms:

Subtract 7 from both sides:

Divide both sides by 4:

.

Now that we know the value of , we can substitute it inside an equation to find . Let's substitute it inside .

So the two numbers are 2 and 13.
