Answer 1

An equation is made when an equality symbol connects two statements or variables.

This means that the equation has a left hand side and a right hand side.

The addition property of equality states that whatever is added to the left hand side of an equation must also be added to the right hand sideof the equation. This ensures balance on both sides.
