Answer:
Well.... First you find all possible exits then make sure no one leaves. Then you take out the adults(If any) to make sure no one is called. Finally light them up. Depending on where they are will depend on how many rounds you use.
Step-by-step explanation:
Just use the coefficients for each variable and put it in a matrix. Is the second question set equal to something? Because then you would put it in place as the question mark. (Did the pic come through?)
So the 3x3 matrix is made up of the coefficients and then to augment the matrix, you add another column at the end with the solutions. Good luck!
Answer:
to simplify this problem the answer would be 12sqrt5 - 6sqrt2 but I cannot explain it.
