Find the missing value of X between 5X+55X +5 equal to 11

Answer: The missing value of XX is 65\frac{6}{5}.

Step-by-step solution

Step 1: Set up the equation

We begin by writing down the given equation that needs to be solved for XX. This equation shows a relationship between XX and known numbers.

Step 2: Isolate the term with X

To find the value of XX, we first need to isolate the term containing XX. We can do this by subtracting the constant term, 55, from both sides of the equation. This maintains the equality as seen in the textbook's approach to finding a missing number through subtraction (Reference 1, 2, 3).

Step 3: Perform subtraction

Now, we perform the subtraction on the right side of the equation. Subtracting 55 from 1111 gives 66. The equation now states that 55 times XX is equal to 66.

Step 4: Solve for X

To find the value of XX, we divide both sides of the equation by 55. This operation isolates XX completely and gives us its numerical value. Dividing 66 by 55 yields the final result for XX.
