Решите уравнение (82+y)6=17 (y-33)9=305 5 (y-2)+3=38 9+2 (14-y)=15

а) (82+y)6=17, (82+y)= 17*6, (82+y)= 102, у=102-82, у = 20,

б) (y-33)9=305, (y-33)=305*9, у-33=2745, у= 2745+33, у = 2778,

в) 5*(y-2)+3=38, 5*(y-2)=38-3, 5*(y-2)=35, y-2 =35/5, y-2 = 7, у =7+2, у=9,

г) 9+2*(14-y)=15, 2*(14-y)= 15-9, 2*(14-y)=6, 14-y=6/2, 14-y=3, -y=3-14, -у=-11, у=11.
