Answer 1

X-8=-3

X= -3 + 8

X=5



8+ x= -9

X= -9 - 8

X= -17


12+ x= 3

X = 3 - 12

X= -9



5 + z = -3

Z= -3 + 5

Z= 2


2+ x= 4+ 6

2+ x = 10

x= 10 - 2

X= 8



15-x-5 = 3-7-1

15- x - 5 = -5

15 - x =. -5 + 5

x = 0+ 15

X= 15

Answer 2

•x-8= -3

x= -3+8

x= +5

•12+x=3

x= 3-12

x= -9

• -7-x = -9

-x= -9+7

-x= -2

x= -2:(-1)

x= +2

•-5+z= -3

+z = -3+5

+z = +2

•-2+x=4+6

-2+x= 10

+x= 10+2

x = 12

•15-x-5= 3-7-1

10-x = -5

x = -5-10

-x = -15

x = -15 (-1)

x= +15
