The value of x in the first question is 3/7.
The value of y in the second question is 17/22
For the first equation given, the first step is to simplify the numbers in the numerator
5(1 - x) + 3(1 +x)
5 - 5x + 3 + 3x
2 - 2x
The equation becomes
Cross multiply
2 - 2x = 8(1 - 2x)
2 - 2x = 8 -16x
Combine similar terms
16x - 2x = 8 - 2
14x = 6
Divide both sides of the equation by 14
x = 6/14
x = 3/7
<em><u>The second question </u></em>
the first step is to simplify the terms in the numerator by combining similar terms
y - 4 + 3y
4y - 4
The second step is to simplify the terms in the denominator by combining similar terms
2y - 3 - 4y
-2y - 3
The equation becomes
=
Cross multiply
20y - 20 = -2y - 3
Combine similar terms
20y + 2y = 20 - 3
22y = 17
Divide both sides of the equation by y
y = 17/22

Answer:
Assuming that there are only 2 flavors of the sweet ⇻ strawberry & orange.
____________________
P (strawberry flavored sweet) = 0.8
P (orange flavored sweet) = ?
____________________
Now, we know that ➳ the value of probability ≤ 1. So, the probability of orange flavored sweets is less than 1.
____________________
So,
P (orange flavored sweet) = 1 - P (strawberry flavored sweet)
P (orange flavored sweet) =
P (orange flavored sweet) =
____________________
✐ The probability that the sweet is orange flavored is <u>0</u><u>.</u><u>2</u>
