The expression \( 2z + 9z \) simplifies to \( 11z \).
Solución
The expression \( 2z + 9z \) involves combining like terms. Both terms have the variable \( z \), so you can add their coefficients (the numerical parts) together:
\[
2z + 9z = (2 + 9)z = 11z
\]
**Equivalent expression:**
\[
11z
\]

Combining like terms is the key here! When you have \( 2z + 9z \), you simply add the coefficients (2 and 9) together. So, \( 2 + 9 = 11 \). Therefore, the expression \( 2z + 9z \) simplifies to \( 11z \). In these types of problems, always look for like terms that can be combined! A common mistake is to forget that similar terms can be added together or to mix up the signs. Just remember to keep your terms organized; it makes everything clearer and simplifies your calculations.
