Answer 1

Given:

The two expressions are

$(y\times 1)+2$

$y+2$

To find:

Whether the given expression are equivalent or non-equivalent.

Solution:

If two expressions are looking different but they are equal after simplification, then they are called equivalent expressions.

The first expression is

$(y\times 1)+2=y+2$

The first expression is equal to the second expression after the simplification.

Therefore, the given expressions are equivalent.
