Is this your equation?
x - 2 - 2 - 3x = 0
-2x - 4 = 0
-2x = 4
x = 4/-2
x = -2
The answer is:
x can either equal *-2* or *you made a mistake*

x-2-2-3x=0
group the numbers wih the same variables. transpose -2 and -2 to the other side of the equation and they will become positive.
x-3x=2+2
-2x=4
(note that the answer of x-3x is -2x because you will follow the sign of the bigger number)
divide both side by -2 so that x will remain on the other side.
-2x/-2=4/-2
x= -2
how will you know if the answer is right?
simply replace the x with the obtained value.
-2-2-2-3(-2)=0
