Hallo anonymous!
3\4 + 1\3 -3 (X-9)=5X-42:6
3/4 + 1/3 - 3 * (x - 9) = 5x -42/6
-3 * (x - 9) - 5x = - 42/6 - 3/4 -1/3
-3x + 27 -5x = - 42/6 - 3/4 -1/3
8x = 27 + 42/6 + 3/4 + 1/3
8x = (27 * 12 + 42 * 2 + 3 * 3 + 1 * 4) / 12 Das KGV von 3;4;6 ist 12
8x = (324 + 84 + 9 + 4) / 12
8x = 421 /12
x = 421 / 96
x = 4,385416666 = 4 + 37/96
Probe:
3/4 + 1/3 - 3 * (x - 9) = 5x -42/6
3/4 + 1/3 - 3 * (4,38541666 - 9) = 5* 4,385416666 -42/6
14,927 = 14,927 !!!
