Решить по 1) 6 (2x+1/6 )= 5 (2,4x +0,2 ) 2) 2 (9x + 3 )= 3 ( 1 + 6x)

12х+1=12х+1                                                      18х+6=3+18х
                                                                             18х-18х=3-6                                                                             х=-3
12х-12х=1-1
х=0

1) 12x+1=12x+1;
     0=0-верно
2) 18x+6=3+18x;
