помогите решить уровнения
1) 140X - 860 = 42240 : 352 = 120 140X = 120 + 860 = 980 X = 980 : 140 = 7 ..................................................... 2) X + 1018 = 850 * 70 = 59500 X = 59500 - 1018 = 58482 ...................................................... 3) ( 28 + X ) * 19 = 1140 28 + X = 1140 : 19 = 60 X = 60 - 28 = 32 .................................................... 4) X * 35 - 32 = 3573 35X = 3573 + 32 = 3605 X = 3605 : 35 = 103 ............................................. 5) 53X = 424 * 15 = 6360 X = 6360 : 53 = 120 ................................ 6) 138X = 64 * 234 = 14979 X = 14976 : 138 = 108.521 ( округляем до 109 )
