Решите уравнение: a) 4,6 - x = -2,5; б) y + 6 \(\frac{9}{16}\) = -8 \(\frac{7}{24}\).

a) 4,6 - x = -2,5 -x = -2,5 - 4,6 -x = -7,1 x = 7,1 б) y + 6 \(\frac{9}{16}\) = -8 \(\frac{7}{24}\) y + \(\frac{105}{16}\) = -\(\frac{199}{24}\) y = -\(\frac{199}{24}\) - \(\frac{105}{16}\) y = -\(\frac{199*2}{24*2}\) - \(\frac{105*3}{16*3}\) y = -\(\frac{398}{48}\) - \(\frac{315}{48}\) y = -\(\frac{713}{48}\) y = -14 \(\frac{41}{48}\)
