Решить уравнение (4/9+х)-2/9=5/9 ; 5+(4y-10)/12=11/12

(4/9 + х) - 2/9 = 5/9
4/9 + х = 5/9 + 2/9 = 7/9
х = 7/9 - 4/9 = 3/9 = 1/3

5 + (4у - 10) : 12 = 11/12
5 + (4у - 10) = 11/12 * 12 = 11
4у - 10 = 11 - 5 = 6
4у = 6 + 10 = 16
у = 16 : 4 = 4

(4/9+x)-2/9=5/9
4/9+x= 5/9+2/9
4/9+x=7/9
x=7/9-4/9
x=3/9сокращаем получается 1/3
