#### 1. What Are Equivalent Expressions?

Equivalent expressions are two or more expressions that have equal outcomes or values. They contain numbers, variables, and operators that can be rearranged to form a different expression but with the same result. For instance, the expressions 2x + 4 and 4 + 2x are equivalent expressions since they have the same value of 6.

#### 2. How to Find Equivalent Expressions?

To find equivalent expressions, you must know the properties of numbers and operations such as the commutative, associative, and distributive properties. You can use these properties to rearrange expressions as you like without changing the value. For instance, the expression 5x + 15y can be rearranged using the distributive property to 5(x + 3y) or using the associative property to (5x + 15y), which still holds the same value.
