Решите уравнения:1)5/14+х+9/14=2/9+9/10;2)(2/3+х)+(1/5+1/3)=9/10+4/5-3/10.Помогите решить...

Решите задачу:

$\frac{5}{14} +x+ \frac{9}{14} = \frac{2}{9} + \frac{9}{10} \\ 1+x= \frac{20+81}{90} \\ 1+x= \frac{101}{90} \\ x= \frac{101}{90} -1 \\ x=1 \frac{11}{90} -1 \\ x= \frac{11}{90} \\ \\ ( \frac{2}{3} +x)+( \frac{1}{5} + \frac{1}{3} )= \frac{9}{10} + \frac{4}{5} - \frac{3}{10} \\ \frac{2}{3} +x+ \frac{1}{5} + \frac{1}{3} =0,9+0,8-0,3 \\ 1,2+x=1,4 \\ x=1,4-1,2 \\ x=0,2$

$( \frac{2}{3} +x)+( \frac{1}{5} + \frac{1}{3} )= \frac{9}{10} + \frac{4}{5} - \frac{3}{10} \\ \frac{2}{3} +x+ \frac{1}{5} + \frac{1}{3} = \frac{27+24-9}{30} \\ 1 \frac{1}{5} +x= \frac{42}{30} \\ x= \frac{42}{30} -1 \frac{1}{5} \\ x= \frac{42}{30} - \frac{6}{5} \\ x= \frac{42-36}{30} \\ x= \frac{6}{30} = \frac{1}{5}$
