Question

Решите уравнение: 2 2/23*(2 16/21*x+4 1/8):1 13/17=5 2/3

Answer 1

2*2/23 * (2*16/21 / x + 4*1/8) / 1*13/17 = 5*2/3

136 / 115 * ( 33 / 8 + 58 / 21x ) = 17/3

33 / 8 + 58 / 21x = 115 / 24

(693x + 464) / 168x = 115 / 24

24 * (693x + 464) = 19320x

16632x + 11136 = 19320x

-2688x = -11136

x = 29 / 7
