one number is 3 times as large as another. Their sum is 48. Find the numbers

Let the first number be x. Let the second number be y. We're given two equations:

1. x = 3y
2. x + y = 48

Substitute equation (1) into equation (2):
3y + y = 48

To solve for y, we type this equation into the search engine and we get:
y = 12

Now, plug y = 12 into equation (1) to solve for x:
x = 3(12)
x = 36
