X+x+x=125

To solve the equation \(X + x + x = 125\), we first combine like terms.

The equation simplifies to:

\[ X + 2x = 125 \]

Now, we can express one variable in terms of the other. For example, if we want to express \(X\) in terms of \(x\), we can rearrange the equation as follows:

\[ X = 125 - 2x \]

Alternatively, if you want to express \(x\) in terms of \(X\), you can rearrange it like this:

\[ 2x = 125 - X \implies x = \frac{125 - X}{2} \]

Without additional information about the relationship between \(X\) and \(x\), this is as far as we can solve the equation. If you have a specific value for either \(X\) or \(x\), we can find the other variable.
