DUE AT 11:59 I NEED HELP NOW

Ok so 6-2x=6x-10x+2
you can either get rid of the variable or the number, imma show u the number
so subtract 6 from both sides
so it'll be -2x=6x-10x+2-6
cause 6 is on the other side
then do 6x-10x=-4x
so -2x=-4x+2-6
then do 2-6=-4
so -2x=-4x-4
then add 4x to both sides
so 2x=-4
divide by 2 on both sides
x=-2
if u need a better explanation tell me
i just tried to type it out asap

Best answer that i found on yahoo ok   set :   x= length of 2nd piece in cm  x- 3= length of 1st piece in cm  x-4= length of 3rd piece in cm  then since you know they all came from the 20 cm ribbon you add them together and set them equal to 20x+ x-3 +x-4 = 20  3x - 7= 20  3x= 27  x= 9  the shortest piece is the third piece which is x- 4  x-4  9-4 = 5  the length of the smallest piece is 5 cm.  the other lengths are  9 cm  6 cm
