Question

решите уравнение
8-х=3 7/9
6 1/2-k=2 5/12
3+a=5/9
x+2 3/7=5 1/2

Answer 1

8-х=3 7/9
х=8-3 7/9
х=7 9/9-3 7/9
х=4 2/9

6 1/2-к=2 5/12
к=6 1/2-2 5/12
к=6 6/12-2 5/12
к=4 1/12

3+а=5/9
а=5/9-3
а=5/9-27/9
а=-22/9
а=-2 4/9

х+2 3/7=5 1/2
х=5 1/2-2 3/7
х=5 7/14-2 6/14
х=77/14-34/14
х=43/14
х=3 1/14
