thanks a lot i really needed that one
To find the number, let's solve the equation.
Let's assume the certain number is represented by "x." According to the given information, 7 times this certain number is equal to 7 times the number itself. Mathematically, we can represent this as:
7x = 7x
This equation indicates that both sides are equal and cancel each other out. Therefore, any value of x will satisfy this equation. In other words, the value of the certain number can be any real number.
