Решите уравнение: 1) x/3 - 2x/9 = x/6 + 1/2 2) y/2-y/8=y/4-1 3) |3 - x| = 5

1) x/3 - 2x/9 = x/6 + 1/2 1) x/3 - 2x/9 - x/6 = 1/2 (6х-4х-3х)/18=1/2 -x/18=1/2 -x=1/2*18 -x=9 x=-9  y/2-y/8=y/4-1  y/2-y/8-y/4=-1 (4y-y-2y)/8=-1 y/8=-1 y=-8 3) |3 - x| = 5 3-x1=5 при 3-х1>=0 x1=<3 x1=-2 3-x2=-5 при 3-х2<0 x2=>3 x2=8
