5/18x + 2 1/2=10 5/6

решите уравнение

4 5/12-5 3/5 х=2 2/3

5 3/5 х = 4 5/12-2 2/3

5 3/5 х = 4 5/12-2 8/12

5 3/5 х=3 17/12-2 8/12

5 3/5 х=1 9/12

5 3/5 х = 1 3/4

х = 1 3/4: 5 3/5

х=7/4: 28/5

х=7/4 * 5/28

х=5/16

5/18 х+2 1/2=10 5/6

5/18 х = 10 5/6-2 1/2

5/18 х = 10 5/6-2 3/6

5/18 х = 8 2/6

5/18 х = 8 1/3

х = 8 1/3: 5/18

х = 25/3 : 5/18

х=25/3 * 18/5

х=30
