Пошаговое объяснение:
1) 5(a+b)=5a+5b
2) -(c+d)=-c-d
3) -2(5-4a)=-10+8a
4) 7(x+y)=7x+7y
5) -10(a-2c)=-10a+20c
6) -7(1/2-14b)=-3.5+98b
7) -8(-4x-3y)=32x+24y
8) 10m-(4n+5)=10m-4n-5
9) 52c-(38b+75a-d)=52c-38b-75a+d
10) 25(-4+1/5b-2c)=-100+5b-50c
11) 42(3/14a-2x+1.5y)=9a-84x+63y
12) 135-(85x+75y+40z)=135-85x-75y-40z
13)75b+(8b-4c+5.2a)=83b-4c+5.2a
