Найдите корень уравнения (х+8/9)*2- 13/18=1 5/6

(Х+8/9)*2=13/18+1 5/6
(Х+8/9)*2= 2 10/18= 2 5/9.
Х+8/9= 2 5/9:2
Х+8/9=23/18=1 5/18
Х=1 5/18-8/9
Х=7/18

( x + 8/9 ) * 2 - 13/18 = 1 5/6
( x + 8/9 ) * 2 = 1 15/18 + 13/18
х + 8/9 = 1 28/18 : 2
x + 8/9 = 2 10/18 : 2
x + 8/9 = 2 5/9 : 2
x + 8/9 = 23/9 : 2
х + 8/9 = 23/18
х = 23/18 - 16/18
х = 7/18
