Mathematics

Answer:

The answer is x=2y-2

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, <em>we need to clear x as function of y.</em>

So, we begin with

y=y(x)=\frac{1}{2}x+1 \Leftrightarrow y-1=\frac{1}{2}x \Leftrightarrow 2y-2=x=x(y)

Therefore

x=2y-2

X/2+1=y  subtract 1 from both sides

x/2=y-1  multiply both sides by 2

x=2y-2
