4 5/14 - (х - 7 3/14) = 2 9/14
61/14 - х + 101/14 = 37/14
-х = (37-61-101)/14
-х = -125/14
х = 8 13/14
А 79-(63+7)=79-70=9
б 43+(23+77)=43+100=143
8 5/9-10=-1 4/9
14 1/6-18 14/27=85/6-500/27=765/54-1000/54=-235/54
-1 4/9+(-235/54)=-13/9-235/54
=-78/54-235/54=-313/54=-5 43/54
Х<u>/6=16
х=16</u>×6
х=96
ответ 96
