Respuesta:

$\frac{4x+1}{3} = \frac{3(x-1)}{7}$

$7(4x+1)=9(4x-1)$

$28x+7=36x-9$

$7=36x-9-28x$

$7 = 8x-9$

$7+9=8x$

$16=8x$

$16/8=x$

$2=x$

$x=2$

$\frac{2x-5}{12} =\frac{-x}{4}-\frac{5}{3}$

$2x-5=-3x-20$

$2x+3x=-20+5$

$5x=-15$

$x=-15/5$

$x=-3$

$\frac{x}{5} +\frac{x}{3} -1=\frac{x}{2}$

$\frac{8x}{15} -1=\frac{x}{2}$

$16x-30=15x$

$-30=15x-16x$

$-30=-x$

$30=x$

$x=30$

$\frac{2x+4}{3} =\frac{x}{6} -3$

$\frac{2(x+2)}{3} =\frac{x}{6} -3$

$4(x+2)=x-18$

$4x+8=x-18$

$4x-x=-18-8$

$3x=-26$

$x=-26/3$

$\frac{x+11}{2} -\frac{2x+3}{5} =5$

$5(x+11)-2(2x+3)=50$

$5x+55-4x-6=50$

$x+49=50$

$x=50-49$

$x=1$

$\frac{5x+1}{6} +\frac{2x+1}{3} =2$

$5x+1+2(2x+1)=12$

$5x+1+4x+2=12$

$9x+3=12$

$9x=9$

$x=9/9$

$x=1$

$\frac{6x+1}{5} =-10+\frac{2x+1}{3}$

$3(6x+1)=5(2x+1)-150$

$18x+3=10x-145$

$18x+3-10x=-145$

$8x+3=-145$

$8x=-145-3$

$8x=-148$

$x=-148/8$

$x=-37/2$

$x-\frac{x}{5} =30$

$\frac{4x}{5} =30$

$4x=30*5$

$4x=150$

$x=150/4$

$x=75/2$
