hej mam zadanie z równań wszystkie obliczenia ! a) 1/2 x = 1/3 x - 1 b) 1/2 - x = - 1/2x c) 1/2 x +1/5 x - 1/10 x = 2

a) 1/2 x = 1/3 x - 1 1/2x-1/3x=-1 1/6x=-1/:1/6 x=-6 b) 1/2 - x = - 1/2x -x+1/2x=-1/2 -0,5x=-1,2/:(-0,5) x=1 c) 1/2 x +1/5 x - 1/10 x = 2 3/5x=2/: 3/5 x=10/3 x=3 i 1/3 licze na naj;);*

a) 1/2 x = 1/3 x - 1 1/2x-1/3x=-1 3/6x-2/6x=-1 1/6x=-1/*6 x=-6 b) 1/2 - x = - 1/2x -x+1/2x=-1/2 -1/2x=-1/2/*(-2) x=1 c) 1/2 x +1/5 x - 1/10 x = 2 5/10x+2/10x-1/10x=2 6/10x=2 /*10 6x=20/:6 x=3 2/6 x=3 1/3 licze na naj ;)

1/2 x = 1/3 x - 1 -1 + 1/3x = 1/2x -1 = 1/2x - 1/3x -1 = 1/6x x = -1 : 1/6 x = -6 1/2 - x = - 1/2x 1/2 = -1/2x + x 1/2 = 1/2x x = 1/2 : 1/2 x = 1 1/2 x +1/5 x - 1/10 x = 2 6/10x = 2 x = 2 : 6/10 x = 3 i 1/3
