10x-9y=24
Y=x-2
X=
Y=

Step-by-step explanation:

10x-9y=24(1)

y=x-2...(2)

Substitute (2) into (1)

10x-9(x-2)=24

10x-9x+18=24

x+18=24

Substrate 18 from both sides

x=6

Substitute the value of x in (2)

y=6-2

y=4

When x=6,y=4

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
