Explicación paso a paso:

$3y-7\le \:y\:+5\\\\3y-7+7\le \:y+5+7\\\\3y\le \:y+12\\\\3y-y\le \:y+12-y\\\\2y\le \:12\\\\y\le \:6$

Y = 8 falso porque y vale 6

$3m+1 > \:5-2m\\3m+1-1 > 5-2m-1\\3m > -2m+4\\\3m+2m > -2m+4+2m\\\5m > 4\\m > \frac{4}{5}$

M = 2 falso porque m vale 4/5

$\frac{2}{3}x+4\ge \:x+1\\\frac{2}{3}x+4-4\ge \:x+1-4\\\frac{2}{3}x\ge \:x-3\\\frac{2}{3}x-x\ge \:x-3-x\\-\frac{1}{3}x\ge \:-3\\\left(-\frac{1}{3}x\right)\left(-1\right)\le \left(-3\right)\left(-1\right)\\\frac{1}{3}x\le \:3\\3\cdot \frac{1}{3}x\le \:3\cdot \:3\\x\le \:9$

x = 9 verdadero porque x vale 9

$-\frac{7}{9}p-\frac{1}{4} < \frac{5}{8}p+\frac{2}{5}\\-\frac{7}{9}p-\frac{1}{4}+\frac{1}{4} < \frac{5}{8}p+\frac{2}{5}+\frac{1}{4}\\-\frac{7}{9}p < \frac{13}{20}+\frac{5}{8}p\\-\frac{7}{9}p-\frac{5}{8}p < \frac{13}{20}+\frac{5}{8}p-\frac{5}{8}p\\-\frac{101}{72}p < \frac{13}{20}\\\left(-\frac{101}{72}p\right)\left(-1\right) > \frac{13\left(-1\right)}{20}\\\frac{101}{72}p > -\frac{13}{20}\\72\cdot \frac{101}{72}p > 72\left(-\frac{13}{20}\right)\\\frac{101p}{101} > \frac{-\frac{234}{5}}{101}\\p > -\frac{234}{505}$

p = 0 falso porque simplificando saldria -0.463 y el 0 esta en negativo
