Problem: Think of a number x. Multiply it by 15. Add y to the result. Subtract 52 from this result. What is the final result?

Solution:
To solve this problem, we need to follow the given steps:
1. Think of a number x.
2. Multiply it by 15.
3. Add y to the result.
4. Subtract 52 from this result.

Step 1: Think of a number x
Let's assume the number x to be 10.

Step 2: Multiply it by 15
Multiply the number x by 15:
10 * 15 = 150

Step 3: Add y to the result
Add the variable y to the previous result:
150 + y = 150 + y

Step 4: Subtract 52 from this result
Subtract 52 from the previous result:
(150 + y) - 52 = 150 + y - 52

Final Result:
The final result of the given expression is 150 + y - 52.

Explanation:
The problem requires us to think of a number x, multiply it by 15, add y to the result, and then subtract 52 from the final result. To solve this, we followed the given steps and obtained the final expression 150 + y - 52.

This expression represents the result when we substitute the value of x with 10, as assumed in step 1. The final result, 150 + y - 52, depends on the value of y, which is not specified in the problem. Therefore, the expression cannot be simplified further without knowing the value of y.

In summary, the final result is represented by the expression 150 + y - 52, where y is the variable representing an unknown value.
