Question

12−5x−4kx=y solve for x

Answer 1

minus 12 both sides
-5x-4kx=y-12
undistribute x
x(-5-4k)=y-12
divide both sides by (-5-4k)
$x=\frac{y-12}{-5-4k}$
$x=\frac{12-y}{4k+5}$

Answer 2

Answer:

The value of the equation is $x=\frac{12-y}{5+4k}$.

Step-by-step explanation:

Consider the provided equation.

$12-5x-4kx=y$

We need to solve the provided equation for x.

Subtract 12 both side.  

$12-12-5x-4kx=y-12$

$-5x-4kx=y-12$

Take -x common as shown:

$-x(5+4k)=y-12$

Divide both sides by 5+4k.

$-x=\frac{y-12}{5+4k}$

$x=\frac{-y+12}{5+4k}$

$x=\frac{12-y}{5+4k}$

Hence, the value of the equation is $x=\frac{12-y}{5+4k}$.
