Пошаговое объяснение:

7/12-х=1/9;

x=7/12-1/9 => НОК(12;9) = 36=>

x=21/36-4/36;

x=17/36.

*************

х-3/4=1/6;

x=1/6+3/4 => НОК(6;4)=12 =>

x=2/12+9/12;

x=11/12.

****************

х+4/9=23/27;

x=23/27-4/9 => НОК(27;9) = 27 =>

x= 23/27 - 12/27;

x=11/27.

**************

9/14+х=5/7;

x=5/7-9/14 =ЮНОК(7;14) = 14 =>
