Answer:
22.5
Step-by-step explanation:
If you divide y/x each ticket costs $2.5, so multiply 2.5x9 and that's your answer. :)
Multiply the first equation by -2 to eliminate a variable so it becomes:
-12x+8y=48
4x-8y=-32
Add them together.
-8x=16
x=-2
Plug it in one equation.
6(2)-4y=-24
12-4y=-24
-4y=-12
y=3
Ordered pair is: (-2,3)
