(3 * x + 8) / 10 - ((9 * x - 9) / 14) = (31 * x - 4) / 14 + (4 * x - 1) / 35 / / - (31 * x - 4) / 14 + (4 * x - 1) / 35

(3 * x + 8) / 10 - ((9 * x - 9) / 14) - ((31 * x - 4) / 14) - ((4 * x - 1) / 35) = 0

(3 * x + 8) / 10 + ( - 1 * (9 * x - 9)) / 14 + ( - 1 * (31 * x - 4)) / 14 + ( - 1 * (4 * x - 1)) / 35 = 0

(14 * 35 * (3 * x + 8)) / (10 * 14 * 35) + ( - 1 * 10 * 35 * (9 * x - 9)) / (10 * 14 * 35) + ( - 1 * 10 * 35 * (31 * x - 4)) / (10 * 14 * 35) + ( - 1 * 10 * 14 * (4 * x - 1)) / (10 * 14 * 35) = 0

14 * 35 * (3 * x + 8) - 1 * 10 * 35 * (9 * x - 9) - 1 * 10 * 35 * (31 * x - 4) - 1 * 10 * 14 * (4 * x - 1) = 0

140 - 1680 * x - 10850 * x - 560 * x + 1400 + 7070 = 0

140 - 12530 * x - 560 * x + 8470 = 0

8610 - 13090 * x = 0

(8610 - 13090 * x) / (10 * 14 * 35) = 0

(8610 - 13090 * x) / (10 * 14 * 35) = 0 / / * 10 * 14 * 35

8610 - 13090 * x = 0

8610 - 13090 * x = 0 / / - 8610 - 13090 * x = - 8610 / / : - 13090

x = - 8610 / ( - 13090)

x = 123 / 187

x = 123 / 187.
