Решите уравнения, срочно надо! Заранее спасибо! 1 5/6-(y+2/3)=1 1/2 -5/7-(m-1)=11/14...

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.
