(12.5 - x) / 5 = (3.6 + x) / 6
6 * (12.5 - x) = 5 * (3.6 + x)
75 - 6x = 18 + 5x
57 = 11x
x = 57 / 11 = 5 $\frac{2}{11}$

(4 $\frac{3}{8}$ x + 5 $\frac{1}{16}$ ) * $\frac{4}{15}$ = $\frac{5}{12}$ x + 2 $\frac{2}{5}$
$( \frac{35}{8}x + \frac{81}{16} ) * \frac{4}{15} = \frac{5}{12}x + \frac{12}{5}$
$\frac{140}{120}x + \frac{324}{240} = \frac{5}{12}x + \frac{12}{5}$
9x/12 = 252/240
x = 252/180 = 1.4 = $1 \frac{2}{5}$
