Question

Pick the story that can be modeled by the equation x + 6 = 15.   Choices: (A)There are x girls and 6 boys in Knight Middle School's chess club. Altogether, there are 15 members in the club. (B)The Knight Middle School's chess club has a total of x members, but 6 members were absent from yesterday's meeting. Only 15 members attended the meeting.

Isolate x:  Analyze the equation x + 6 = 15 to find the value of x. Subtract 6 from both sides to isolate x. Calculation: x = 15 - 6 = 9. Interpret x:  Interpret the value of x in the context of the stories provided. x represents the number of members or attendees, depending on the story. Match x to Stories:  Match the value of x to the stories: (A) x = 9 girls, and there are 6 boys, making a total of 9 + 6 = 15 members. (B) x = 9 total members, but 6 were absent, so only 15 - 6 = 9 attended, which doesn't match the given x value.
