adults=24

children=36

Step-by-step explanation:

x+y=60

400x+250y=18600

x=60-y

400(60-y)+250y=18600

y=36.

solve this expression then u will get the answer for y.

x+36=60

x=24.

x = ± 6i

step-by-step explanation:

x^2 = -36

take the square root of each side

sqrt(x^2) = sqrt(-36)

we know sqrt(ab) = sqrt(a) sqrt(b)

x = ±sqrt(36) sqrt(-1)

we know that sqrt (-1) = i

x = ± 6i
