25x-3/8-3x=5/2 решить уравнение

25x - 3/8 - 3x = 5/2;

25х - 3х = 5/2 + 3/8;

22х = 20/8 + 3/8;

22х = 23/8;

22х = 2,875;

х = 2,875 : 22;

х = 0,1306818181818182;

25 * 0,1306818181818182 - 3/8 - 3 * 0,1306818181818182 = 5/2;

3,267045454545455 - 0,375 - 0,3920454545454545 = 2,5;

2,892045454545455 - 0,3920454545454545 = 2,5;

2,5 = 2,5.
