Forming the Equation:
Let's assume the number Meera thinks of is 'x'. According to the given information, when Meera adds 19 to the number and divides the sum by something, she gets 8. Let's call this 'y'. So we can form the equation as follows:

(x + 19) / y = 8

Solving the Equation:
To find the value of 'x', we need to solve the equation.

To do that, we need to find the value of 'y' first. From the given information, it is not mentioned what Meera divides the sum by. So we are missing a piece of information here. Without knowing the value of 'y', we cannot solve the equation and find the value of 'x'.

Explanation:
In this question, we are asked to form an equation and find the value of 'x' by solving it. However, there is missing information in the problem statement. We are not given what Meera divides the sum by, which is represented by 'y' in the equation.

To solve the equation, we need the value of 'y' because it directly affects the outcome of the equation. Without this information, we cannot proceed with finding the value of 'x'. It is important to have all the required information to solve a problem accurately.

In conclusion, the given problem is incomplete as it does not provide all the necessary information to solve the equation and find the value of 'x'. It is important to pay attention to all the details and ensure that all the required information is provided in order to solve a problem successfully.
