б)-x= - 5/12-(+11/12)
решите!!!

Answer 1

1) - X = 715 - 1415 = ( - 715)
X = 715
2) - X = - 512 - 1112 = - 1612 = - 86 = - 43 = - 1 13

Answer 2

а) -х =7/15-(+14/15)                 б) -х=-5/12-(+11/12)
7/15-14/15= -7/15                       -5/12-11/12= -16/12
-х=-7/15                                   -х= -16/12
х=7/15                                    х=16/12
