Answer 1

-5 +17-41+42= 13

12-9+36-17-7=15

25-55-122-183= - 335

-145-39-83+124= - 143

-366+114-68+32=- 288

 

x x-7=-2

x = -2 + 7

x =5

 

-13-x=-21

x=-21 +13

x=-8

 

x-(-7)=-12

x=-12-7

x=-19

 

13+x=-(-12)

x=12-13

x=-1

 

47+x=-14

x=-14-47

x=-61

 

x+(-56)=95

x=95+56

x=151

 

-7-x=-6

x= -6+7

x=1

 

x+(-11)=-[-(-2)]

x=-2 -11

x= -13
