Решить уравнение 5 класс х+8 4/29=12; 5 7/18-(х-2 5/18)=1 11/18

Х=12-8 4/29
х=3 25/29

5 7/18-х+2 5/18=1 11/18
7 12/18-х=1 11/18
-х=1 11/18-7 12/18
х=6 1/18

X + 8 4/29 = 12 
X = 12 - 8 4/29 
X = 11 29/29 - 8 4/29 
X = 3 25/29 

5 7/18 - ( X - 2 5/18 ) = 1 11/18
5 7/18 - X + 2 5/18 = 1 11/18
7 12/18 - X = 1 11/18
7 12/18 - 1 11/18 = X 
X = 6 1/18
X = 6 1/18
