An equation is a statement of equality between two algebraic expressions. A very crucial skill in solving word problems is learning how to represent the unknown value or values with the correct algebraic expressions and relate the expressions to form an equation based on the given conditions. To determine the solution, simply perform the inverse operations with respect to the equation formed. To verify whether a number or value is a solution to the equation, just substitute the number to the variable in the equation and check to see whether the resulting number sentence is true. Learn about algebraic expressions and equations by helping Phineas win a bet with his friends on completing a trip around the world in just 80 days.
