Answer 2

¡Hola!

Respuesta:

a. $Es\:x=-87$

b. $Es\:x=-\frac{1}{27}$

c. $Es\:x=\frac{1}{7}$

Explicación paso a paso:

a. $2\left(\frac{x-1}{4}-4\right)-3\left(\frac{2x}{9}-1\right)=9$

   $\frac{x-1}{2}-8-\frac{2x}{3}+3=9\\\\\frac{x-1}{2}-\frac{2x}{3}-5=9\\\\\frac{-x-3}{6}-5=9\\\\-\frac{x}{6}-\frac{3}{6}-5=9\\\\-\frac{x}{6}-\frac{1}{2}-5=9\\\\\mathrm{Multiplicamos\:ambos\:lados\:por\:}6:\\\\-\frac{x}{6}\cdot \:6-\frac{1}{2}\cdot \:6-5\cdot \:6=9\cdot \:6\\\\-x-3-30=54\\\\-x-33=54\\\\-x = 54+33\\\\-x=87\\\\x=87/-1\\\\x=-87$

b. $-3\left(\frac{7x}{3}-\frac{2x}{4}\right)-\frac{5x+1}{3}=\frac{11x}{6}$

   $-3\left(\frac{7x}{3}-\frac{x}{2}\right)-\frac{5x+1}{3}=\frac{11x}{6}\\\\-\frac{11x}{2}-\frac{5x+1}{3}=\frac{11x}{6}\\\\Minimo\:comun\:multiplo\:de:2\:y\:3\\\\\frac{-33x-\left(5x+1\right)\cdot \:2}{6}\\\\\frac{-33x-2\left(5x+1\right)}{6}\\\\\frac{-43x-2}{6}\\\\-\frac{43x}{6}-\frac{1}{3}=\frac{11x}{6}\\\\\mathrm{Multiplicamos\:ambos\:lados\:por\:}6:\\\\-\frac{43x}{6}\cdot \:6-\frac{1}{3}\cdot \:6=\frac{11x}{6}\cdot \:6\\\\-43x-2=11x\\\\-43-11x=2\\\\-54x=2\\\\x=\frac{2}{-54}\\\\x=-\frac{1}{27}$

c. $-6\left(\frac{4x}{9}-\frac{8x-1}{3}\right)-\frac{5x+2}{3}=-1$

     $6\cdot \frac{-20x+3}{9}-\frac{5x+2}{3}=-1\\\\-\frac{-40x+6}{3}-\frac{5x+2}{3}=-1\\\\\frac{-\left(-40x+6\right)-\left(5x+2\right)}{3}=-1\\\\\frac{40x-6-5x-2}{3}=-1\\\\\frac{35x-8}{3}=-1\\\\\frac{35x}{3}-\frac{8}{3}=-1\\\\\mathrm{Multiplicamos\:ambos\:lados\:por\:}3:\\\\\frac{35x}{3}\cdot \:3-\frac{8}{3}\cdot \:3=-1\cdot \:3\\\\35x-8=-3\\\\35x=-3+8\\\\35x=5\\\\x=\frac{5}{35}\\\\x=\frac{1}{7}$
