Chapter 11.2
Solving two-step linear equations using addition and subtraction: ax + b = c
What You'll Learn
Identify the operations involved in two-step linear equations of the form ax + b = c
Apply inverse operations in the correct order to isolate the variable
Solve two-step equations using visual balance models and algebraic methods
Translate word problems into two-step linear equations and solve them
Verify solutions by substituting back into the original equation
What You'll Practice
1
Solving equations visually using balance tiles before writing algebraic steps
2
Isolating variables by undoing addition and subtraction first, then multiplication and division
3
Working with equations where the variable appears on either side of the equal sign
4
Solving real-world word problems involving discounts, fees, and total costs
Why This Matters
Mastering two-step linear equations builds your foundation for all future algebra. You'll use this skill to solve real-world problems like calculating costs, discounts, and budgets, and it's essential for tackling more complex equations in higher-level math courses.
