An equation is a mathematical relation between two equal quantities. For example, $2=2$ is an equation because the quantity on the left-hand side is equal to the quantity on the right-hand side. Sometimes, equations contain variables. $x+3=5$ In this case, the expression $x+3$ is equal to $5.$ Solving this equation would produce the value of the variable that makes the equation true.
