#### Solutions

Chapter 1, Problem 1RE
To determine

## To describe: The property of the real numbers being used. 3x+2y=2y+3x .

Expert Solution

Commutative property of additivity is used in the expression.

### Explanation of Solution

Given information:

The expression, 3x+2y=2y+3x .

The commutative property is a property in which, a+b=b+a .it means when we add two numbers as, a+b ,and then we add b+a and equate both these both are equal by this property.

It is like two constants are added and they are equal the the commutative property is there.

As the two numbers are added order doesn’t matter.

For example: 4+3=3+47=7

Apply the property , a+b=b+a .

3x+2y=2y+3x3x3x=2y2y0=0 .

The above expression is satisfied to the commutative property.
