Worked example
Practice set: 3x + 4 = 19; 5x − 2 = 3x + 10; 4(x − 1) = 20
- Answers: x = 5; x = 6; x = 6.
- For each problem, identify the first operation before calculating.
- Substitute every answer into the original equation.
Guided practice
Try the next step before revealing the answer.
Practice balancing and solving linear equations, reveal hints before answers, and verify each result.
Work each problem on paper, name the operation used on both sides, and substitute your answer. Use the workspace for hints rather than copying the final value first.
