Number 17 is smaller of the two number whose sum is 51. Find the other number.

Answer

To solve the problem, we need to find the other number when one number is given as 17 and their sum is 51. Here’s how we can do it step by step:

### Step-by-Step Solution:

1. **Identify the Known Values**: We know that one number is 17 and the sum of the two numbers is 51.

2. **Set Up the Equation**: Let the other number be represented by \( x \). According to the problem, we can write the equation:
\[ x + 17 = 51 \]

3. **Isolate \( x \)**: To find \( x \), we need to isolate it on one side of the equation. We can do this by subtracting 17 from both sides:
\[ x = 51 - 17 \]

4. **Perform the Calculation**: Now, we will calculate \( 51 - 17 \):
\[ 51 - 17 = 34 \]

5. **State the Result**: Therefore, the other number is:
\[ x = 34 \]

6. **Conclusion**: We can conclude that the other number is 34, which is indeed greater than 17.

### Final Answer:
The other number is **34**.
