for example is 52. Can you send me websites that explain problems as such?
Thank you! :)

We will call the two numbers x and y?

and such that one is 3 times as large as the other.

Let numbers be x and 3x
x + 3x = 52
4x = 52
x = 13
3x = 39
Numbers are 13 and 39

there are multiple ways to view problems like this, but there is a condition missing here...
say the sum is 52
x+y = 52
y = 52 - x
x = 52 - y
but you can't actually solve the system with just 1 equation and 2 unknowns...you need to know something else about the system before the question can be answered without use of a free parameter...

Normally we need an extra condition. For example, find two numbers which are odd and add to 52. That would for example be 35 and 17.
I feel you should reframe your question.

x+y=52
x=3y
3y +y =52
4y = 52
y = 52/4
y=13
x= 3*13 = 39
13+39 = 52

If, as you suggest, you call them x and y, then all you can say is
x + y = 52
From that, you can rearrange to get either x or y in terms of the other:
x = 52 - y
y = 52 - x
Without further information, that's all you can do.
