Analyze Equation x - 15 = 45:  Step 1: Analyze the equation x - 15 = 45. To solve for x, add 15 to both sides of the equation. x - 15 + 15 = 45 + 15 x = 60 Interpret Calculated Value:  Step 2: Interpret the stories with the calculated value of x = 60. (A) Malia started with x lollipops, used 15, and had 45 left. x - 15 = 45 matches the equation given. (B) Malia had 45 lollipops and divided them into 15 bags, which does not relate to subtracting 15 from x. This would be modeled by 45 / 15 = x, which simplifies to x = 3
