Solving Equations with Variables on Both Sides

To solve equations with variables on both sides, bring all the variable terms to one side of the equation. Use the Distributive Property, if necessary, collect like terms, and simplify.
To solve equations with variables on both sides, simplify as much as you can on both sides before you apply inverse operations to isolate the variable.
After finding the solution, substitute to check your answer. In real life situations, ask yourself if the answer is reasonable.
