Question

make x the subject of the formula in y=x+4/x-3

Answer 1

You can multiply the whole equation by x-3 leading to y(x-3) = x+4
@prasheelasingh do you know what to do next?

Answer 2

I hope you understand it with this.
First, let's isolate the denominator x-3 by multiplying the whole equation by x-3
\[(x-3) [y = \frac{ x+4 }{ x-3 }]\]
Therefore,
\[y(x-3) =x+4 \]
Let distribute y in the left side
\[xy-3y = x+4\]
To make x as the subject of the equation, we need to isolate all terms having x. Hence
\[xy -x = 4+3y\]
Then factor out x and solve for x.
\[x (y-1) = 3y+4\]
Therefore,
\[x = \frac{ 3y+4 }{ y-1 }\]
