Step-by-step explanation:

Let be "a", "b", and "c" all real numbers, the Transitive property of equalities states that :

If $a=b$ and $b=c$ , then $a=c$

You can observe that if two numbers are equal to the same number, then all this numbers are equal to each other.

For example, applying the Transitive property of equalities to:

$x+3=2x+1$

And solve for "x":

$3-1=2x-x\\\\x=2$
