Question

Пожалуйста помогите найти корень уравнения 1) -x - (41 3/5 - 45 1/3)= -9 7/15 2) (20,2 - 27 3/7) - y = 19 32/35

Answer 1

1)

-x - (41 3/5 - 45 1/3)= -9 7/15

-x - ( 41 9/15 - 45 5/15) = -9 7/15

-x - ( -3 11/15) = -9 7/15

-x + 3 11/15 = -9 7/15

x = 3 11/15 + 9 7/15

x = 12 18/15

x = 13 1/5

2)

(20,2 - 27 3/7) - y = 19 32/35

(20 1/5 - 27 3/7) - y = 19 32/35

(20 7/35 - 27 15/35) - y = 19 32/35

-7 8/35 - y = 19 32/35

y = -7 8/35 - 19 32/35

y = -26 40/35

y = -27 1/7
