Question

помогите решить 1015 номер 1 и 2

Answer 1

$5x-3 \frac{1}{2} =4 \frac{2}{3} \\ 5x=4 \frac{2}{3} +3 \frac{1}{2} \\ 5x=4+3+( \frac{4+3}{6} ) \\ 5x=8 \frac{1}{6} \\ x=8 \frac{1}{6} :5 \\ x= \frac{49}{6}* \frac{1}{5} \\ x= \frac{49}{30} \\ x=1 \frac{19}{30}$

$8x+11 \frac{2}{11}=15 \\ 8x=15-11 \frac{2}{11} \\ 8x=3 \frac{9}{11} \\ x=3 \frac{9}{11} :8 \\ x= \frac{42}{11} * \frac{1}{8} \\ x= \frac{21}{44}$
