We are required to find the value of x for which :
[tex]w(x)\text{ + t(x) = x}[/tex]
Let us step through the values of x:
When x =1:
w(x) = -1, t(x) = -3
[tex]\begin{gathered} w(x)\text{ + t(x) = -1 +(-3)} \\ =\text{ -1 - 3} \\ =\text{ -4} \end{gathered}[/tex]
This is not equal to 1. This is wrong
When x =2:
w(x) = 3, t(x) = -1
[tex]\begin{gathered} w(x)\text{ + t(x) = 3 + (-1)} \\ =\text{ 3 - 1} \\ =\text{ 2} \end{gathered}[/tex]
This is equal to 2. This is correct.
Hence, the value of x for which w(x) + t(x) =x is 2
Answer:
2 (Option B)
