Решите уровнения 1)(х-7/15)+5/8=17/24
2)4/5(х+1/60)=2/3

1) (x-7/15)+5/8=17/24                         2) 4/5(x+1/60)=2/3

x=17/24-5/8+5/15                                4/5x+75=2/3

x=170/240-35/240+16/240                  4/5x=2/3-75

x=6 7/24                                               4/5x=26/75

                                                             x=26/75*4/5

                                                             x=13/30

                                                             Ответ: х=13/30
