Answer 1

$y- frac{12}{31} =5 \ y=5+ frac{12}{31} \ y=5 frac{12}{31} \ \ 2z+ frac{32}{17} =10/*17 \ \ 34z+32=170 \ 34z=170-32 \ 34z=138 \ z= frac{138}{34} \ \ x=4 frac{2}{34} \ \ x=4 frac{1}{17}$

Answer 2

у-12/31=5
у=5+12/31
у=5 12/31

Ответ:5 12/31

2z+32/17=10
2z=10-32/17
2z=170/17-32/17
2z=138/17
z=138/17*1/2
z=69/17
z=4 1/17

Ответ:4 1/17
