A equation is an algebraic equally that is true only for some values of the variables. These values are called solutions of the equation.
- Sides of an equation
- unknown: are the letters that appear in the equation.
- Solutions: are the values that make the equality true.
- To solve an equation is to find the simplest equivalent equation that gives us the solution.
