There is no "answer", X=6 is complete in itself. There is nothing to solve. What is the value of X? Well, it's equal to 6.
A variable like "x" can have any value. If you have a complete equation, like 9x + 12 = 100, a specific value of x will make the equation true; other values will make it false. But here, you don't have an equation, so any value will do for x.
