Question

tariq said you can write an equation by setting an expression equal to itself Would an equation like this be true.explain.

Answer 1

Answer: Yes it is true. We can write an equation by setting an expression equal to itself.

Step-by-step explanation:

Let we take an expression say 2x.

Since we know that any expression is equal to itself, so we can write it as 2x=2x, which does not give any solution or we can say this equation has no solution but we can not say it is false because they are actually equal.

Therefore, we can write an equation by setting an expression equal to itself. It would be a true equattion.

Answer 2

Yes it would.
An equation says two things are equal.
So if you have an expression x + 1 and you set it equal to x + 1
you have x + 1 = x + 1, which is a true and valid equation, not saying it's any useful but it is an equation.
