Question

Математика: Раскрыть скобки: 1. (a-b+-b)= 3-(x-y+3)= a-(a-b+c)= (x-+y)= (x--x)= 2. (m-p+q)-p= (a-b++b-1)= m-(m-p+q)= (m-p++p-3)= m-(p-m)=

1. a-b+c-a+b = c3-x+y-3 = -x+y = y-xa-a+b-c = b-cx-y-x-y = -2yx-y+y+x = 2x2. m-p+q-p = m-2p+qa-b+1-a-b+1 = -2b+2m-m+p-q = p-qm-p+5-m-p+3 = -2p+8m-p+m = 2m - p...
