The answer is -0.8 welcome
8x-6y=-96 add to this -4 times the second equation...
-8x-12y=-48
___________
-18y=-144
y=8, this makes 8x-6y=-96 become:
8x-48=-96
8x=-48
x=-6
so the solution to the system of equations is the point:
(-6,8)
Counter clockwise means it goes backwards so -90°
After the 90° counter clockwise rotation the coordinates are (4,-3)
I believe the answer is c
X represents the amount of children's tickets
y represents the amount of adult's tickets
8(x+y) = 54
