Решите уравнения, срочно надо! Заранее спасибо!

1 5/6-(y+2/3)=1 1/2

-5/7-(m-1)=11/14

Очень срочно!!!

11/6*y +11/6*2/3 =3/2;(1 5/6 -2/3 ) -y =1 1/2;1 1/6  - y = 1 1/2  ;y =1 1/6 -1 1/2 ;y = - 1/3.----------------------------11/6  - y - 2/3 = 3/2;11-6y -4 =9;-6y = 9+4 -11;-6y = 2;y =-1/3.======================-5/7 -(m-1)=  11/4;m-1 =-5/7 -11/14;m-1 =- - 3/2;m=1-3/2;m =-1/2.---------------------------10 -14(m-1) =11;-10 -11 =14(m-1);-21 =14(m-1);-3 =2(m-1);m-1 =-3/2;m=1-3/2 ;m= -1/2.=================
