Find the value of x when 6 - 2x = 5x - 9x + 10.

The value of x is

Step-by-step explanation:

6 - 2x = 5x - 9x + 10 {add the like terms}

6 - 2x = - 4x + 10 {add (-6) to both side}

6 - 2x - 6 = - 4x + 10 - 6

-2x = - 4x + 4 {add 4x to both sides}

-2x + 4x = - 4x + 4 + 4x

2x = 4 {divide both sides by 2}

2x/2x = 4/2

x = 2
