Answer 1

1/7•[x-0,(23)]=5/14
x-0,(23)=5/14:1/7
x-23/99=5/14•7
x-23/99=5/2
x=5/2+23/99
x=541/198

Answer 2

[tex] \frac{1}{7} *x- \frac{1}{7} * \frac{23}{99} = \frac{5}{14} \frac{1}{7} x- \frac{23}{693} = \frac{5}{14} \frac{1}{7}x= \frac{5}{14} + \frac{23}{693}amplificam fractia \frac{5}{14} [/tex] cu 49,5[tex] \frac{1}{7}x= \frac{247,5}{693} + \frac{23}{693} \frac{1}{7}x= \frac{270,5}{693}$x= \frac{270,5}{693} *7simplificam 7 si 693 si in loc de 7 ne ramane 1 si in loc de 693 ne ramane 99[tex]x=270,5$
