rozwiąż równania ; a) 1/3 x - 2 = x+2 b) 1-6/7x=4/7 c) 6(1/4x - 2)=18 d) x /6 - 1/6=1 e) -2(2x-1)= x/3 . Jakby co to 1/4 to jedna czwarta .. proszę o pomoc i z góry dziękuje daje 40 ;]

a) 1/3 x - 2 = x+2 1/3x-x=2+2 -²/₃x=4 x=-6 b) 1-6/7x=4/7 -6/7x=4/7-1 -6/7x=-3/7 x=¹/₂ c) 6(1/4x - 2)=18 1,5x-12=18 1,5x=18+12 1,5x=30 x=20 d) x /6 - 1/6=1/*6 x-1=6 x=6+1 x=7 e) -2(2x-1)= x/3/*3 -12x+6=x -12x-x=-6 -13x=-6 x=⁶/₁₃      

a) 1/3 x - 2 = x + 2 1/3 x - x = 2 + 2 -2/3 x = 4 I : (-2/3) x= -6   b) 1-6/7x=4/7 -6/7x=4/7-1 -6/7x=-3/7 I:(-6/7) x=1/2   c) 6(1/4x-2)=18 3/2x-12=18 3/2x=18+12 3/2x=30 I:3/2 x=20   d)x/6-1/6=1 I *6 x-1=6 x=6+1 x=7
