Нужно решит уравнения по быстрее

Пошаговое объяснение:

(51/14)x = 102

x = 102 * 14/51

x = 28

11x + 3 4/7 = 2

11x = 2 - 3 4/7

11x = -1 4/7

x = -1 4/7 : 11

x = -11/7 * 1/11

x = -1/7

(3/8)x + 6/7 = 5 - (5/6)x

(3/8)x + (5/6)x = 5 - 6/7

(9/24)x + (20/24)x = 4 1/7

(29/24)x = 4 1/7

x = 4 1/7 : 29/24

x = 29/7 * 24/29

x = 24/7

x = 3 3/7

21(x - 5) = 2(10 - 7x)

21x - 105 = 20 - 14x

21x + 14x = 20+105

35x = 125

x = 125:35

x = 3 4/7

2/1 ( 2x + 1/3) = 2 1/6 - (x/2 - 5/33)

4x + 2/3 = 2 1/6 - x/2 + 5/33

4x + 2/3 = 2 11/66 + 10/66 - x/2

4x + 44/66 = 2 21/66 - x/2

4x + x/2 = 2 21/66 - 44/66

4x + (1/2)x = 1 43/66

(4 1/2)x = 109/66

x = 109/66 : 4 1/2

x = 109/66 : 9/2

x = 109/66 * 2/9

x = 109/297
