4x + 8 = 2x -10                    (1st line)
4x - 2x + 8 = 2x -2x -10      (2nd Line)
2x + 8 = -10                         (3rd Line)
2x + 8 - 8 = -10 - 8              (4th Line)
6x = -2                                  (5th Line)
6x/ 6 =-2/6                           (6th Line)

X= - 1/3

2x + 8 - 8 = -10 - 8  
=> 2x = -18
thus, x=-9 and not  -1/3

Line 4 is  x/4   x  4
It didn't really look that way on the picture.

anonymous · Answer

in the 2nd line : x/4 +3 - 3 = -12 -3 
which is equal to : x/4=-15 , right?

anonymous · Answer

Yeah
