Question

Rearrange y=1/2x+1 to make x the subject of the formula

Answer 1

x/2+1=y  subtract 1 from both sides

x/2=y-1  multiply both sides by 2

x=2y-2

Answer 2

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, we need to clear x as function of y.

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

$x=2y-2$
