Решить уравнения! 1) (x+4)+15=75 2) (x*4)+15=75 3) (x/4)+15=75 4) (x-4)+15=75 5) 410+(x+104)=604 6) (x-104)-410=604 7) 104+(x*8)=192 8) (604-(x-104)=410

1)(х+4)+15=75      2) (х*4)+15=75   3) (х/4)+15=75         4) (Х-4)+15=75     5)410+(Х+104)=604

   75-16=60               75-15=60            (75-15)*4=240         (75-15)+4=64        (604-410)-104=90

   60-4=56                 60/4=15               Х=240                     Х=64                  Х=90

   х=56                       х=15

6) (Х-104)-410=604                 7)104+(Х*8)=192       

     (604+410)+104=1118            (192-104)/8=11     

      Х=1118                                  Х=11
