Question

During a sleepover, Carissa played karaoke with her friends. Her song was 6 minutes long. She had already sung for 4 minutes. Which equation could be used to see how much longer she will have to sing?

x + 2 = 6
x + 4 = 10
x + 4 = 6
x − 4 = 6

Answer 1

Answer: x + 4 = 6
Explanation:correct

Answer 2

x + 4 = 6

Explanation:

In the question, it says that the song they're singing is 6 minutes long, and that she already sang for 4 minutes. That said, something (x) added to 4 will equal to 6, and that x will be Carissa's answer to how much longer she would sing.
