Решите уравнения: 86 + 35z = 331, ( 0 + 2m) - 45 = 127, ( 120 + 3p) -97 = 233.

1) 86 + 35z = 331.35z = 331 - 86.35z = 245.z = 245 / 35.z = 7.2) (0 + 2m) - 45 = 127.2m - 45 = 127.2m = 127 + 45.2m = 172.m = 172 / 2.m = 86.3) (120 + 3p) - 97 = 233.120 + 3p - 97 = 233.3p = 233 - 120 + 97.3p = 210.p = 210 / 3.p = 70.Ответ: 1) z = 7; 2) m = 86; 3) p = 70.
