c) 4 = x + 20

d) 4 = x – 10

e) 7 = x + 8

f) 0 = x + 12

g) -3 = x + 10

h) 15 = x + 1


​

Answer 1

18= x + 20

- x= 20 - 18

- x= 2 >>.(-1)

x= - 2

4= x + 20

- x= 20 - 4

- x= 16 >>.(-1)

x= - 16

4= x - 10

- x= - 10 - 4

- x= - 14 >>.(-1)

x= 14

7= x + 8

- x= 8 - 7

- x= 1 >>.(-1)

x= - 1

0= x + 12

- x= 12 >>.(-1)

x= - 12

- 3= x + 10

- x= 10 + 3

- x= 13 >>.(-1)

x= - 13

15= x + 1

- x= 1 - 15

- x= - 14 >>.(-1)

x= 14
