Answer:
The answer is [tex]x=2y-2[/tex]
Step-by-step explanation:
The question gives us y as function of x, and is asking us to give the formula of x as function of y, in order to do that, we need to clear x as function of y.
So, we begin with
[tex]y=y(x)=\frac{1}{2}x+1 \Leftrightarrow y-1=\frac{1}{2}x \Leftrightarrow 2y-2=x=x(y)[/tex]
Therefore
[tex]x=2y-2[/tex]
