Explanation Procedure used: “ Problem-solving Steps 1. UNDERSTAND the problem. During this step, become comfortable with the problem. Some ways of doing this are as follows: a). Read and reread the problem b). Construct a drawing. c) Propose a solution and check. Pay careful attention to how you check your proposed solution. This will help when writing an equation to model the problem. d) Choose a variable to represents an unknown. Use this variable to represent any other unknowns. 2. TRANSLATE the problem into an equation. 3. SOLVE the equation. 4. INTERPRET the results: check the proposed solution in the stated problem and state the conclusion.” Calculation: From example 4, observe that the distance from Chicago to Boston is 963 miles. UNDERSTAND: Let x be the distance from Chicago to Los Angeles then the distance from Chicago to Boston is x − 1091 . The resulting statement is, the distance from Chicago to Los Angeles and the distance from Chicago to Boston is the total distance. TRANSLATE: Translate the statement “the distance from Chicago to Los Angeles and the distance from Chicago to Boston is the total distance” into an algebraic expression as follows. In words : the distance from Chicago to Los Angeles and Chicago to Boston is total distance ↓ ↓ ↓ Translate: x + ( x − 1091 ) = 3017 That is, the algebraic expression is x + ( x − 1091 ) = 3017
