a)7×+3=9+2× b)9-8×=15-6× c)6(3+2×)=2(×-4) d)4(¼-5×)-⅓(9-6×)=1 Proszę o rozwiązania (szczegółowo)!!

a)7×+3=9+2× 7x - 2x = 9 - 3 5x = 6/:5 x = 1 i 1/5 b)9-8×=15-6× -8x+6x = 15 - 9 -2x = 6/:2 -1x = 3 x = -3 c)6(3+2×)=2(×-4) 18+12x = 2x - 8 12x - 2x = -18 - 8 10x = -26/:10 x = - 2 i 3/5 d)4(¼-5×)-⅓(9-6×)=1 1 - 20x - 3 - 2x = 1 -22x = 3 -3 = 22x/:22 -3/22 = x Pozdrawiam =)

a)7x+3=9+2x 7x-2x=9-3 5x=6 x=6/5 x=1.2 b)9-8x=15-6x -8x+6x=15-9 -2x=6 x=6/-2 x=-3 c)6(3+2x)=2(x-4) 18+12x=2x-8 12x-2x=-8-18 10x=-26 x=-26/10 x=-2.6 d)4(1/4-5x)-1/3(9-6x)=1 1-20x-3-2x=1 -20x-2x=1+3-1 -22x=3 x=3/-22 x=-3/22
