1/3х+2(2/3х-1/6)=-1 1/6

Question

1/3х+2(2/3х-1/6)=-1 1/6

Answer 1

1/3х+4/3х-2/6+7/6=0; 5/3х+5/6=0; 1/3х+1/6=0; х не равен нулю ( делить на ноль нельзя. х в знаменателе) х=-1/6:1/3; х=-3/6; х=-1/2=-0,5

Answer 2

1/3х + 2*(2/3х - 1/6) = - 1 1/6, 1/3х + 4/3х - 2/6 = - 7/6, 5/3х = - 7/6 + 2/6, 10/6х = - 5/6, х = - 5/6 : 10/6 = - 5/6 * 6/10, х = - 1/2 (или - 0,5)
