Answer:
6x+2y=34
6x=34-2y
x=(34-2y)÷6........1st euation
2x-7y=-27.....2nd equation
putting the value of x from equation 1st in equation 2nd we will get
2(34-2y)÷6-7y=-27
68-4y-42y=-27×6
-44y=-162-68
-44y=-230
y=230÷44
y=5.2
again putting the value of x in equation 1st
6x=34-2×5.2
x=23.6÷6
x=3.9
Answer:
500 adult tickets
Step-by-step explanation:
Let adult and student tickets be x and y.
The number equation is
x + y = 980
The value equation is
5x + 2y = 3460
Let's multiply the first by two and subtract it from the second...
5x + 2y = 3460
-(2x + 2y = 1960)
and we get
3x = 1500
x = 500 adult tickets
y = 480 student tickets
D. X cubed
E. X to the negative 3
