Пошаговое объяснение:

(27/5z+31/3)*3/5=1/6z+61/2;

27/5z*3/5+31/3*3/5=1/6z+61/2;

27*3/5*5z+31*3/3*5=1/6z+61/2;

81/25z+31/5=1/6z+61/2;

81/25z+31/5-1/6z=61/2;

461/150z+31/5=61/2;

461/150z=61/2-31/5;

461/150z=305/10-62/10;

461/150z=305-62/10;

461/150z=243/10;

z=243/10*150/461;

z=243*150/10*461;

z=36450/4610;

z=3645/461
