4-{-2+[-3-3+x-1]-5}=3

4-{-2+[x-7]-5}=3

4-(-2+x-7-5)=3

4-(x-14)=3

4-x+14=3

-x=3-4-14

-x=-15

x=15

2+{3-[7-(x-5)-8]+6}=1

2+{3-[7-x+5-8]+6}=1

2+[3-(-x-10)+6]=1

2+(3+x+10+6)=1

2+x+19=1

x=1-19-2

x=-20

6-{4+[3-(x-1)+5]-6}=8

6-[4+(3-x+1+5)-6]=8

6-[4+(-x+9)-6]=8

6-(4-x+9-6)=8

6-(-x+7)=8

6+x-7=8

x=8+7-6

x=9

Sper ca te-am ajutat :)
