Question

Find the value of $x$for which each of the following statements becomes true:

$45+37=x+45$

Answer 1

If $a$ and $b$are two whole numbers, then $a+b=b+a.$This property is called the commutative property of addition.

by comparing both RHS to LHS, we get:

$45+37=x+45$

$\therefore x=37.$

Hence, the value of $x$ is $37.$
