3 1/2 :(1/6 х+5/8)=2 1/3
1/6 х+5/8=3 1/2 : 2 1/3
1/6 х+5/8=7/2 : 7/3
1/6 х+5/8=7/2 * 3/7
1/6 х+5/8=3/2=1 1/2
1/6 х=1 1/2 - 5/8
1/6 х=1 4/8 - 5/8
1/6 х=7/8
х=7/8 : 1/6
х=7/8 * 6
х=42/8=5 1/4

3 3/8 :(1/14 х+5/7)=2 1/10
1/14 х+5/7=3 3/8 : 2 1/10
1/14 х+5/7=27/8 * 10/21
1/14 х+5/7=45/28
1/14 х=45/28 - 5/7
1/14 х=45/28 - 20/28
1/14 х=25/28
х=25/28 : 1/14
х=25/28 * 14
х=25/2=12 1/2

45 * (2 7/9 х+1 2/15 х)=176
45 * (2 70/90 х+1 12/90 х)=176
3 82/90 х=176 : 45
3 41/45 х=3 41/45
х=1

(4 2/7 у - 1 1/6) * 84=82
30/7 у - 1 1/6=82/84
30/7 у - 1 1/6=41/42
30/7 у=41/42+1 1/6
30/7 у=41/42+1 7/42
30/7 у=2 6/42=2 1/7
у=2 1/7 : 30/7
у=15/7 * 7/30
у=1/2
