Two friends, Becky and Lucia, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Becky's hair is already 30 centimeters long and grows at a constant rate of 2 centimeters per month. Lucia's hair is 12 centimeters and growing at a speed of 3 centimeters per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?

**Title: How to Use Systems of Equations in Real-World Scenarios**

Write a system of equations to describe the situation below, solve using any method, and fill in the blanks.

**Scenario:**  
Two friends, Becky and Lucia, are growing out their hair. They plan to cut it off at a certain point and donate it to a charity that makes wigs for people with cancer. Becky’s hair is already 30 centimeters long and grows at a constant rate of 2 centimeters per month. Lucia’s hair is 12 centimeters long and growing at a speed of 3 centimeters per month. If the girls get their hair cut on a certain day, they will have exactly the same length to donate. How long will their hair be? How long will that take?

Their hair will be ___ centimeters in ___ months.

**Instructions:**

1. **Set Up the Equations:**
   - Let \( x \) be the number of months it takes for their hair to reach the same length.
   - Becky’s hair equation: \( 30 + 2x \)
   - Lucia’s hair equation: \( 12 + 3x \)

2. **Solve the System of Equations:**
   - Set the two equations equal to each other:  
     \( 30 + 2x = 12 + 3x \)

3. **Find the Solution:**
   - Solve for \( x \) to find the number of months.

4. **Calculate the Length:**
   - Substitute \( x \) back into either equation to find the length of the hair at that time.

**Submit your answer:**  
Their hair will be ______ centimeters in ______ months.

**Note:** There are no graphs or diagrams included in this problem.
