Решение уравнение: 1)6m+m-35=21 2)17n+14n-145=134 3)5n+9n+32=200
6m+m-35=21 7m=21+35 7m=56 M=8 17n+14n-145=134 36n=134+145 36n=279 N=7,75
14n=168 N=12
1.1. 6m + m - 35 = 21 = 7m - 35 = 21
7m = 35 + 21
7m = 56
2. m = 56 / 7 = 8
2.1. =21n(как в прошлом) - 145 = 134
21n = 145 + 134 = 279
2. n = 279 / 21 = 279/21
3.1. 14n + 32 = 200
2.14n = 200 - 32 = 168
3.n = 168 / 14 = 12
