Identify correct equation:  Let's identify the correct equation to model the problem. We know 45 students saw the afternoon showing and there were 87 students in total. The equation should represent all students, so: m + 45 = 87 Solve equation:  Now, solve the equation m + 45 = 87 to find m. Subtract 45 from both sides to isolate m: m + 45 - 45 = 87 - 45 m = 42
