Final answer:
The value of x that makes the equation true is 7, and when simplified the equation remains as x = 7. Any value of x other than 7 makes the equation false, and when simplified, the equation turns into an incorrect statement.
Step-by-step explanation:
The value of x that makes the equation true is 7. When we substitute x = 7 into the equation, we get 7 = 7, which is a true statement. So, x = 7 is a solution to the equation.
When we simplify the equation, it remains as x = 7 because there are no other terms or variables involved.
A value of x that makes the equation false is any number other than 7. For example, if we substitute x = 5 into the equation, we get 5 = 7, which is false.
When simplified, the equation turns into 5 = 7, which is false.
