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=(y-12)/(-5-4k)`

`x=(12-y)/(4k+5)`

Answer 2

The value of the equation is
`x=(12-y)/(5+4k)`.

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=(y-12)/(5+4k)`

`x=(-y+12)/(5+4k)`

`x=(12-y)/(5+4k)`

Hence, the value of the equation is
`x=(12-y)/(5+4k)`.
