Question

6(5/12-1 1/6x)-15(2/3x-2 1/5)-35,5 ; якщо x=-3/17

Answer 1

$6( \frac{5}{12} - 1 \frac{1}{6}x) - 15( \frac{2}{3}x - 2 \frac{1}{5} ) - 35.5 \\ 6( \frac{5}{12} - \frac{7}{6} x) - 15( \frac{2}{3} x - 2 \frac{1}{5} ) - 35.5 \\ 6( \frac{5}{12} - \frac{7}{6} x) - 15( \frac{2}{3} x - \frac{15}{5} ) - 35.5 \\ 6( \frac{5}{12} - \frac{7}{6} x) - 15( \frac{2}{3} x - \frac{15}{5} ) - \frac{71}{2} \\ \frac{5}{2} - 7x - 15( \frac{2}{3} x - \frac{11}{5} ) - \frac{71}{2} \\ \frac{5}{2} - 7x - 10x + 33 - \frac{71}{2} \\ 0 - 7x - 10x \\ 0 - 17x \\ - 17$
