Решить уравнения 1) ( х + 12/13 ) - 1 11/13 = 1 1/13 2) 14/15 - ( 2/3 - x ) = 1.8

( х + 12/13 ) - 1 11/13 = 1 1/13
 х + 12/13 = 1 11/13 + 1 1/13
х+12/13=24/13+14/13
х+12/13=38/13
х=38/13-12/13
х= 26/13
х= 2

14/15 - ( 2/3 - x ) = 1.8
14/15-2/3+х=1,8
14/15-10/15+х=1,8
4/15+х=1,8
х=1,8-4/15
х=1  8/10-4/15
х=18/10-4/15
х=9/5-4/15
х=27/15-4/15
х=23/15
х=1  8/15
