Question

Помогите решить (((7x - 3) / 8 + 16) / x + 8 )*7=77

Answer 1

(((7x - 3) / 8 + 16) / x + 8 ) * 7 = 77,

(((7x - 3) / 8 + 16) / x + 8 ) = 77 : 7,

(((7x - 3) / 8 + 16) / x + 8 ) = 11,

((7x - 3) / 8 + 16) / x = 11 - 8,

((7x - 3) / 8 + 16) / x = 3,

((7x - 3) / 8 + 16) = 3 * х,

((7x - 3) / 8 + 16) = 3х,

(7x - 3) / 8 = 3х - 16

7x - 3 =  8 * (3х - 16),

7х - 3 = 24х - 128,

24х - 7х = 128 - 3,

17х = 125,

х = 7 6/17
