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

The answer is
`x=2y-2`

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)=(1)/(2)x+1 \Leftrightarrow y-1=(1)/(2)x \Leftrightarrow 2y-2=x=x(y)`

Therefore

`x=2y-2`
