Решите уравнение: (1 целая5/18-2 целых4/27) * 5.4x=9 целых1/2+2

целых 1/4

(23/18 - 58/27) * (54/10) x = 9.5·x + 2.25

(23·3 - 58·2) / 54 · (54/10) ·x = 9.5·x+2.25

(69 - 116) / 54 · (54/10) ·x = 9.5·x+2.25

(-47/54) · (54/10) ·x = 9.5·x + 2.25

- 4.7·x - 9.5·x = 2.25

- 14.2 x = 2.25

x = 2.25 : (- 14.2) = - 225 : 1420 = - 45 : 284 = - (45/284)
