Answer: The equations are correct as the addition of individual and group acts must be equal to the total duration of the act.

Step-by-step explanation

As the addition of individual and group acts must be equal to the total duration of the acts, then, the equations should be:


12x+6y=120
4x+y=30

which is equal to what the classmates wrote. Thus, they are correct.
