Решите уравнение:
а) 34,98x − 33,98x + 24x = 87,29;
б) 56,289x + 45,07x − 100,359x = 52,15;
в) 25,5x − 13,08x − 12,42x = 52,907;
г) 186,37x − 95,327x − 52,043x = 12,48.
34,98x − 33,98x + 24x = 87,29
x + 24x = 87,29
25x = 87,29
x = 87,29 : 25
x = 3,4916
56,289x + 45,07x − 100,359x = 52,15
101,359x − 100,359x = 52,15
x = 52,15
25,5x − 13,08x − 12,42x = 52,907
12,42x − 12,42x = 52,907
0 = 52,907 − уравнение не имеет решений
186,37x − 95,327x − 52,043x = 12,48
91,043x − 52,043x = 12,48
39x = 12,48
x = 12,48 : 39
x = 0,32
