हिंदी में जवाब दो: A number is such that when you double it and add 7, you get 33. Form an equation and find the number.

Answer: The number is 13.

Step-by-step solution

Step 1: Define the variable

Let's represent the unknown number with a variable. We'll use $x$ to denote the number we need to find.

Step 2: Formulate the equation

According to the problem statement, if we double the number ( $2x$ ) and add 7, the result is 33. This translates directly into the equation $2x + 7 = 33$ .

Step 3: Isolate the variable term

To solve for $x$ , we first need to isolate the term containing $x$ . We can do this by subtracting 7 from both sides of the equation.

Step 4: Solve for the number

Now that we have $2x = 26$ , we can find the value of $x$ by dividing both sides of the equation by 2.
