Caitlyn needs to solve the equation: 2(3x+1)=3(2-x). after copying the problem correctly she uses the properties of algebra to solve for x in 5 steps. there is a reason the justifies each step. what is the justification that caitlyn used for each step? name each property of algebra.
step 1 6x + 2 = 6 - 3x
step 2 2 = 6 - 9x
step 3 -4 = -9x
step 4 4/9 = x
step 5 x = 4/9

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
