Question

¿quien me ayuda con estas ecuaciones?​

Answer 1

Respuesta:

$1) x=-2\\2) x=-2\\3)x=\frac{15}{2}$

Explicación paso a paso:

$\frac{1}{3} +\frac{5}{4} x-\frac{5}{6} =\frac{3}{2} x\\\\\frac{1}{3} -\frac{5}{6} =\frac{3}{2} x-\frac{5}{4} x\\\\-\frac{1}{2} =\frac{1}{4} x\\\\\frac{4}{1}(-\frac{1}{2}) = x\\\\-2=x\\\\\\ \frac{1}{2} +\frac{x}{5} +\frac{1}{10} =-\frac{x}{4} -\frac{3}{10} \\\\\frac{1}{2} +\frac{1}{5}x +\frac{1}{10} =-\frac{1}{4}x -\frac{3}{10}\\\\\frac{1}{5}x +\frac{1}{4}x = -\frac{3}{10}-\frac{1}{2}-\frac{1}{10} \\\\\frac{9}{20}x=-\frac{9}{10}\\\\x=-\frac{9}{10}(\frac{20}{9})\\\\x=-2$

$\frac{1}{3} (-\frac{5}{7}x+\frac{6}{7} )=1-\frac{1}{3}x\\\\-\frac{5}{21}x+\frac{6}{21} =1-\frac{1}{3}x\\\\-\frac{5}{21}x+\frac{6}{21} =1-\frac{1}{3}x\\\\-\frac{5}{21}x+\frac{1}{3}x =1-\frac{6}{21}\\\\\frac{2}{21}x =\frac{5}{7}\\\\x =\frac{5}{7}(\frac{21}{2})\\\\x =\frac{15}{2}$
