1) g=-y+c/x, solve for X

Sindrei [870]

Answer:

the solution $x = \frac{c}{g-y}$

Step-by-step explanation:

<u>Step 1:-</u>

Given problem $g=\frac{-y+c}{x}$

here l.cm is x

$g = \frac{x y+c}{x}$

cross multiplication we get ,

$g x = x y +c$

<u>Step 2</u>:-

subtracting x y on both sides , we get

$g x - x y = c$

taking common 'x' we get,

$x(g-y) = c$

<u>Final answer</u>:-

$x = \frac{c}{g-y}$
