Option C:
[tex]$x-y= \frac{1}{2}[/tex]
Solution:
Given data:
[tex]$x=\frac{1}{4}[/tex]
[tex]y=-x[/tex]
To find x - y:
Substitute y = -x.
[tex]x-y=x-(-x)[/tex]
[tex]=x+x[/tex]
[tex]=2x[/tex]
Substitute [tex]x=\frac{1}{4}[/tex], we get
[tex]$=2\times \frac{1}{4}[/tex]
Cancel the common factor in 2 and 4, we get
[tex]$= \frac{1}{2}[/tex]
[tex]$x-y= \frac{1}{2}[/tex]
Option C is the correct answer.
