2 answers:
X=10 Y=1
thats your answer hope it helps ;P
3x - 5y = 20
(5; y) - put x = 5 to the equation
3 · 5 - 5y = 20
15 - 5y = 20 |-15
-5y = 5 |:(-5)
y = -1
Answer: (5; -1)
(x; 2) - put y = 2 to the equation
3x - 5 · 2 = 20
3x - 10 = 20 |+10
3x = 30 |:3
x = 10
Answer: (10; 2)

This sample of students is likely to be unbiased because they were chosen randomly.
21.6 ÷ 0.4 = 54 times for green
21.6 ÷ 0.6 = 36 times for purple
Together, 90 beads. Separately, 54 green and 36 purple.
The markup rate is 25%.
$30.00 - $24.00 = $6.00
24 x 25%
24 x .25 = 6
Hope this helps. :)
