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:
18 days
Step-by-step explanation:
Let x represent number of days.
We have been given that Brandy's watch falls 1 second every day. So Brandy's watch will fall seconds behind in x days.
We are also told that Brandy set her watch 4 seconds behind, so Brady's watch will be behind by total seconds in x days.
Since Brady's watch is 22 seconds behind, so we will equate by 22 to solve for x as:
Therefore, Brandy set her watch 18 days ago.
