Answer 1

Para resolução do exercício, tire o M.M.C das frações e isole a incógnita:

$\dfrac{5x-2}{2}-\dfrac{1+x}{7}\leq3+\dfrac{x}{14}\\ \\\dfrac{7\cdot(5x-2)-2\cdot(1+x)}{14}\leq\dfrac{14\cdot3+1\cdot x}{14}\\ \\35x-14-2-2x\leq42+x\\35x-2x-x\leq42+14+2\\32x=58\\x\leq\frac{58}{32}\;(:2)\\\boxed{x\leq\frac{29}{16}}$

Bons estudos!
