Which expression is equivalent to the model provided

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

so answer is D – 9y + 5y
