**Equivalent expressions are expressions that work the same even though they look different.**

**If two algebraic expressions are equivalent, then the two expressions have the same value when we plug in the same value(s) for the variable(s).**

Two expressions are said to be equivalent if they have the same value irrespective of the value of the variable(s) in them.

**Example1 **

the two expressions 3y+5y−3+8 and 8y+5 equivalent

because if we solve 3y+5y−3+8 we get (3y+5y) = 8y and (-3+8) = 5

so it becomes 8y+5 so its equivalent?

**Example 2**

For given expression, select one correct equivalent expression from the given options.

**8y + 4y + 2y**

**A** – 11y

**B** – y + 13

**C** – 7y – 6y

**D** – 9y + 5y

9y + 5y = 14y = 8y + 4y + 2y

### What are equivalent expressions?

Ans: **Equivalent expressions are expressions that look different but resolve to same** **value**
