Calculati: (7-9y)/(2)+14<=(6y-10)/(3)-19y

Answer 1

$\frac{(7 - 9y)}{(2)} + 14 \leqslant \frac{(6y - 10)}{(3)} - 19y = > 3(7 - 9y) + 84 \leqslant 2(6y - 10) - 144y = > 21 - 27y + 84 \leqslant 12y - 20 - 144y = > 105 - 27y \leqslant - 102y - 20 = > - 27y + 102y \leqslant - 20 - 105 = > 75y \leqslant - 125 = > y \leqslant - \frac{5}{3}$
