Giải thích các bước giải:
$\frac{3x}{7}-\frac{2x}{3}=\frac{10}{21}\to \,\,\,\,\,\,\,x=-2$
$\frac{1}{2}-\frac{13}{12}\le x\le \frac{1}{24}-\frac{-5}{24}\to \,\,\,\,\,\,x=0$
$\left( \frac{3}{8}-\frac{1}{5} \right)+\left( \frac{5}{8}-x \right)=\frac{1}{5}\,\,\,\,\,\,\,\to x=0,6$
$2015+\left| 2014-2x \right|\,\,\,\,\to x=1007$
$\left( 3-\frac{3}{2} \right)\left( 3-\frac{4}{3} \right)\left( 3-\frac{5}{4} \right)\left( 3-\frac{6}{5} \right)\,\,\,\,=7,875$
$25\left( -5 \right).\left( -0,4 \right).\left( -0,2 \right)\,\,\,\,\,=-10$
$31\frac{6}{13}+5\frac{9}{41}-36\frac{6}{13}\,\,\,\,\,=0,21951$
$\frac{1}{2011}+\frac{2012.2010}{2011}-2000\,\,\,\,\,\,=13,0009$
$0,25+\frac{3}{5}-\left( \frac{1}{8}-\frac{2}{5}+1\frac{1}{4} \right)\,\,\,\,\,\,=-0,125$
$x+5,6=7,1\,\,\,\,\,\to \,x=1,5$
