Answer:
1.5 or infinite
Step-by-step explanation:
For the second one, 8x+4=16, suppose x is 1.5 (1 1/2), then 8x1.5 is 12, then 12+4 is 16.
As for the first one, their is infinite possibilities. If x equals 3 and y is 2, then 8x3=24 and 4x2=8, and 24-8=16. Another example is if x equals 4 and y is 4. Then 8x4=32 and 4x4=16, then 32-16=16. And one final example to make sure you understand. X equals 10 and y equals 20. 8x10=80 and 4x16=64, then 80-64=16.

Answer:
24
Step-by-step explanation:
Let p, d, r represent the numbers of premium, deluxe, and regular tickets sold, respectively.
p + d + r = 155 . . . . . . . number of tickets sold
8p +3d +r = 409 . . . . . revenue from tickets sold
d - p = 19 . . . . . . . . . . . relation between deluxe and premium tickets
Using the third equation, we can substitute d=19+p in the other two equations.
p + (19+p) +r = 155
8p +3(19+p) +r = 409
Subtracting the first of these equations from the second, we get ...
(11p +r +57) -(2p +r +19) = (409) -(155)
9p = 216 . . . . . . subtract 38 and simplify
p = 24 . . . . . . . . divide by 9
24 premium tickets were sold.
