Oblicz x : a) 6x+2=-2x+6 b) -5x-7=-8x+2 c) 3(x-1)+(2x-1)=6x+2 d) -4(2x-6)=3x-1 Z góry dzięki :)

a) 6x+2=-2x+6 6x+2x=6-2 8x=4 /:8 x=0,5 b) -5x-7=-8x+2 -5x+8x=2+7 3x=9 /:3 x=3 c) 3(x-1)+(2x-1)=6x+2 3x-3+2x-1=6x+2 3x+2x-6x=2+3+1 -1x=6 /:-1 x= -6 d) -4(2x-6)=3x-1 -8x+24=3x-1 -8x-3x= -1-24 -11x= -25 /:-11 x= 25/11 ( ułamek)
