Question

a)-x= 7/15 - (+14/15)
б)-x= - 5/12-(+11/12)
решите!!!

Answer 1

1) - X = 7\15 - 14\15 = ( - 7\15)
X = 7\15
2) - X = - 5\12 - 11\12 = - 16\12 = - 8\6 = - 4\3 = - 1 1\3

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
