Пошаговое объяснение:
-4(x+4+y)=-4x-4y-16
-10(2+x+y)=-10x-10y-20
-9(x+7+y)=-9x-9y-63
-3(a+10-b)=-3a+3b-30
15(c-d-3)=15c-15d-45
-12(-x-y+2)=12x+12y-24
3(a-10-b)=3a-3b-30
-19(2-x)+20=-38+19x+20=19x-18
-15(x+4)+60=-15x-60+60=-15x
16-4(2+a)=16-8-4a=-4a+8
-18+8(4-x)=-18+32-8x=-8x+14
29-3(t-8)=29-3t+24=-3t+53
-a+(2a-b)+2b=-a+2a-b+2b=a+b
3b-(18+b)+8=3b-18-b+8=2b-10
