Lesson 23: Solving Two Step Equations Expressions and Equations
Solving Two-Step Equations • When we solve equations, we do it in reverse order of operations (generally). • We solve these equations the same way we solve one step equations: our goal and process is still the same.
Example • Evaluate for . • Solve
