[tex]x = \frac{13}{80} [/tex]
[tex] \frac{7}{16} - x = \frac{3}{20} + \frac{1}{8} [/tex]
[tex] - x = \frac{3}{20} + \frac{1}{8} - \frac{7}{16} [/tex]
[tex] - x = \frac{8 \times 3}{8 \times 20} + \frac{20 \times 1}{20 \times 8} - \frac{10 \times 7}{10 \times 16} [/tex]
[tex] - x = \frac{24}{160} + \frac{20}{160} - \frac{70}{160} [/tex]
[tex] - x = \frac{24 + 20 - 70}{160} [/tex]
[tex] - x = - \frac{26}{160} [/tex]
[tex]x = \frac{26}{160} [/tex]
