$(\frac{5}{8} -\frac{1}{4} -\frac{1}{12} +\frac{1}{6} )x=(\frac{15}{24} -\frac{6}{24} -\frac{2}{24} +\frac{4}{24} )x=(\frac{15-6-2+4}{24} )x=\frac{11}{24} x \\ \\ (\frac{5}{7}+\frac{1}{4} +\frac{3}{14} +1\frac{3}{4} )y=(\frac{20}{28} +\frac{7}{28} +\frac{6}{28} +1\frac{21}{28} )y=1\frac{54}{28} y=1\frac{27}{14} y=2\frac{13}{14} y$
