(2.4x - 1.26) / (1/2 - 1/3) = (1.3x - 0.5) / (1/10 - 1/9);
(2.4x - 1.26) / (1/6) = (1.3x - 0.5) / (-1/90);
(2.4x - 1.26) = ((1.3x - 0.5) * (1/6)) / (-1/90);
(2.4x - 1.26) = ((1.3x - 0.5) * (15/90)) / (-1/90);
(2.4x - 1.26) = ((1.3x - 0.5) * (15 * 90)) / (-1 * 90);
(2.4x - 1.26) = -(1.3x - 0.5) * 15;
2.4x = -19.5x + 7.5 + 1.26;
21.9x = 8.76;
x = 8.76 / 21.9 = (876 * 10) / (219 * 100) = (292 * 10) / (73 * 100) = 4 / 10 = 0.4;
x = 0.4;
