Question

помогите пж решите уравнением

Answer 1

10 6/10 - ( 7 3/10 - у) = 4 9/10
10 6/10 - 7 3/10 + у = 4 9/10
3 3/10 + у = 4 9/10
У = 4 9/10 - 3 3/10
У = 1 6/10


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


17 18/35 - (n +4 23/35) = 9 12/35
17 18/35 - n - 4 23/35 = 9 12/35
12 30/35 - n = 9 12/35
12 30/35 - 9 12/35 = n
3 18/35 = n
