Solución
The phrase "50 less than twice a number" can be translated into an algebraic expression using the variable \( n \) to represent the unknown number.
1. **Twice a number:** This means two times the number \( n \), which is written as \( 2n \).
2. **50 less than twice a number:** This means you subtract 50 from the expression "twice a number."
Putting it all together:
\[
2n - 50
\]
**Final Algebraic Expression:** \( 2n - 50 \)

To translate "50 less than twice a number" into an algebraic expression, start with "twice a number," which can be expressed as \( 2n \). Then subtract 50 from that: the complete expression is \( 2n - 50 \). If you stumble upon similar phrases in the future, remember that "less than" indicates subtraction and requires careful attention to the order of the terms. For example, if the phrase said "twice the number less than 50," the expression would be \( 50 - 2n \) instead.
