Question

Помогите решить 2 уравнения снизу

Answer 1

а) 55/8-y-1/12= 23/6

165-24y-2=92

24y=71

y= 2 23/24

б) 71/21+ k - 118/21= 18/7

71+21k-118=54

21k= 101

k= 4 17/21

Answer 2

а)6 7/8 -(y+1/12) = 3 5/6

y+1/12 = 6 7/8 - 3 5/6

y+1/12 = 6 21/24 - 3 20/24

y+1/12 = 3 1/24

y = 3 1/24 - 2/24

y = 2 25/24 - 2/24

y = 2 23/24

б)(3 8/21 + k) - 5 13/21 = 2 4/7

3 8/21 + k = 2 4/7 + 5 13/21

3 8/21 + k = 2 12/21 + 5 13/21

3 8/21 + k = 7 25/21

k = 7 25/21 - 3 8/21

k = 4 17/21
