Question

реши уравнений:532 - х / 2 = 277 14859 - С * 9 = 9045

Answer 1

1) 14859 - с * 9 = 9045                       2) 532 - х : 2 = 277
                                                            -х = 277 * 2 - 532
-с = 9045 : 9 - 14859                              -х = 22
-с = - 13854                                            х = -22
 с = 13854                                            532 + 22 : 2 = 277
14859-13854*9=9045
