Problem 8 - Introductory Algebra for College Students

Question

Use the commutative property of addition to write an equivalent algebraic expression. $$x+7$$

Step-by-Step Solution

Answer

The equivalent algebraic expression for \(x + 7\) using the commutative property of addition is \(7 + x\).

Step 1: Understand Commutative Property

The commutative property states that the order in which two numbers are added does not affect the sum, that is, if 'a' and 'b' are any two numbers, then \(a + b = b + a\). Therefore, we will apply this property to the given expression.

Step 2: Application of Commutative Property

In the given expression \(x + 7\), 'x' and '7' are adding. Using the commutative property of addition, this can be rewritten as \(7 + x\).
