Answer 1

$\displaystyle \frac{\frac{3}{4} }{\frac{1}{2}m+\frac{1}{4} }+\frac{2}{3}=2,m\neq -\frac{1}{2}\\\\ \\\frac{\frac{3}{4} }{\frac{2m+1}{4} }+\frac{2}{3}=2\\\\ \\\frac{3}{2m+1}+\frac{2}{3}=2\\ \\\frac{3}{2m+1}=2-\frac{2}{3}\\\\\frac{3}{2m+1}=\frac{4}{3}\\\\9=4(2m+1)\\9=8m+4\\-8m=4-9\\-8m=-5\\\\m=\frac{5}{8}$
