Answer:
Neither
Step-by-step explanation:
To verify, we substitute the values in the equations:

however, the value should be 4. Hence this equation does not satisfy the co-ordinate.

Answer:
QRS=38
Step-by-step explanation:
90-52=38
A. 12*x + 2*y = 90
6*x + 2*y = 60
To write system of equation you just need to sum all solo and ensemble acts and make it equal to how much they will last for.
B. Here we can multiply second equation with negative 1 and add it to first equation.
6x = 30
x = 5
now we replace x in any of 2 equations to get y.
30+2y = 60
2y = 30
y=15
Solo acts are 5 minutes long and ensemble acts are 15 minutes long
B: -8
8 times 1 = 8, and since there is a negative in front of the 1 when you are multiplying, it should be -8/
