Are you sure you posted the entire question?

7n = 7n

if 7 times a certain number is subtracted from 6, the result is 5 times the number. what is the number?

6-7n = 5n

Solve for n.

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.
