7. Ten years from now, Alex’s age will be 3 times her presentage. Find Alex’s age now.

Let \( x \) represent Alex's current age.

According to the problem:

1. Ten years from now, Alex's age will be \( x + 10 \).
2. We are told that this future age is three times her current age, or \( 3x \).

Setting up the equation:

\[
x + 10 = 3x
\]

### Solving for \( x \):

1. Subtract \( x \) from both sides:

   \[
   10 = 2x
   \]

2. Divide both sides by 2:

   \[
   x = 5
   \]

### Conclusion:
Alex's current age is **5 years**.
