Как решить уровнение (4n+12): 8=136

4n + 12 = 136 * 8
4n + 12 = 1088
4n = 1088 - 12
4n = 1076
n = 1076 : 4
n = 269

4n+12=136:8                                                                                                                 4n+12=17                                                                                                                      4n=17-12                                                                                                                       4n=5
