Chapter 2: Q9. (page 66)

Simplify the expression.
$x + 6 + 11$

Short Answer

Expert verified

The simplified expression is $x + 17$ .

Step by step solution

Step-1 – What are real numbers?

Real numbers are simply the combination of Whole numbers, Integers, Rational and Irrational numbers in the number system.

Step-2 – Commutative Property of Addition of Real Numbers:

Suppose a, b, and c is three real numbers.

Commutative Property of Addition:

Property: a + b = b + a

If you add two real numbers in any order, the sum will always be the same.

Example: 5 + 2 = 2 + 5 = 7

Step-3 – Evaluate the expression

Commutative property of Addition states, if you add two real numbers in any order, the sum will always be the same.

Evaluate the expression:

To evaluate the expression $x + 6 + 11$ , the term $x$ is a variable. The terms $6$ and $11$ are constants.

Using the Commutative property of addition, adding like terms,

localid="1650327879578" $\begin{array}{l} x + 6 + 11 \\ x + (6 + 11) \\ x + (11 + 6) (CommutativePropertyofAddition) \\ x + 17 \end{array}$
