6x- 3(2x-1) = 5 + x 18x - 3 --------- - X = 6(x+1) ...3 2x-3.......6x - 1 ------- = ----------- ...2........... 3 musiałem wstawić kropki zamiast spacja bo mi przesówało w lewo tak dla info.

6x - 3(2x-1) = 5 + x 6x - 6x + 3 = 5 + x 6x - x - 6x= 5-3 5x - 6x = 2 x=-2 2) 6x-1 - x = 6x +6 -x = 7 x=-7 3) 3(2x-3) = 2(6x-1) 6x-9 = 12x - 2 6x - 12x = 9-2 -6x = 7 (-6) x=-1 1/6

6x- 3(2x-1) = 5 + x 6x - 6x + 3 = 5 + x x = -2 18x - 3 --------- - X = 6(x+1) ...3 6x - 1 - x = 6x + 6 -1 - x = 6 -x = 7 x = -7 2x-3.......6x - 1 ------- = ----------- ...2........... 3 x - 1,5 = 2x - 1/3 -x = 1,5 - 1/3 x = 1/3 - 1,5 x = - 7/6
