💭 Part 5: Reflection and Problem-Solving Strategies
13. Fill in the blanks about solving linear equations:
To solve 4x + 7 = 23, first I would __________ 7 from both sides, then __________ both sides by 4. The solution is x = __________.
14. Match the equation-solving step with its purpose:
1. Subtract 5 from both sides
2. Divide both sides by 3
3. Substitute x = 4 back into original equation
4. Collect like terms
A. To isolate the variable
B. To check the solution
C. To simplify the equation
D. To eliminate a constant term
