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

According to Tariq, it would be:

a + b = b + a

Which is known as "Commutative Property" 

In short, the equation would be true

Hope this helps!

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.
