1)-7+5+3-2=-1

2)-2×(-3)-6÷(+6)=6-1=5

3)(-2)²-(-3)³-(-1)³‐(-1)⁴=4-(-27)-(-1)-(+1)=31

4)=(-3)²-(-7)²+(-5)²⁴÷(+5)²²=9-49+(-5)²=-40+25=-15

5)-4-2x=14

-2x-4=14

-2x=14+4

-2x=18

x=18÷(-2)

x=-9

6)-4-2x>=-10

-2x-4>=-10

-2x>=-10+4

-2x>=-6

x>=-6÷(-2)

x>=3

1)+3-5+4-6=-4

2)=32+(-5)=27

3)=-8-9-1-(-1)=-17

4)(-3)²-(-2)²+(-5)¹⁸÷(+5)¹⁶=9-4+(-5)²=5+25=30

5)-9-4x=27

-4x-9=27

-4x=27+9

-4x=36

x=36÷(-4)

x=-9

6)-9-4x>sau=-21

-4x-9>=-21

-4x>=-21+9

-4x>=-12

x>=-12÷(-4)

x>=3

x {+○○,+3}
