Решите уравнение 1) (1 целых 1/12+3.75) - (-x) = 4.5 2) - (5 целых 2/3-1.6) - x=6 целых 1/3 3) x - (7 целых 5/9 - 5 целых 1/6) = -3.5 4) x - (-4.6+3 целых 4/7) = -8 целых 1/14

1) (1 1/12 + 3,75) - ( - х) = 4,5;

(13/12 + 375/100) + х = 45/10;

29/10 + х = 45/10;

х = 45/10 - 29/6;

х = - 10/30 = - 1/3.

2) - (5 2/3 - 1,6) - х = 6 1/3;

- (17/3 - 16/10) - х = 19/3;

х = - 19/3 + 61/15;

х = - 34/15 = - 2 4/15.

3) х - (7 5/9 - 5 1/6) = - 3,5;

х = (68/9 - 31/6) - 3 5/10;

х = 43/18 - 35/10;

х = - 200/180 = - 10/9 = - 1 1/9.

4) x - ( - 4 6/10 + 3 4/7) = - 8 1/14;

х + 72/70 = - 113/14;

х = - 113/14 - 72/70;

х = - 635/70 = - 9 1/14.
