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.
