I'll only show you one. Try the rest yourself.

1:
x - 4 = 9
Add 4 to both sides,
x-4+4 = 9+4
x = 13

Answer:

1. x - 4 = 9

x = 9 + 4

x = 13

2. X-12=21

x = 21+12

x = 33

3. 32=X-13

x = 32 +13

x = 45

4. X-12=17

x = 17+12

x = 29

5. -6+x=19

x = 19+6

x = 25

6. X-7=92

x = 92+7

x = 99

7. X-5=12

x = 12+5

x = 17

8. 33=x-35

x = 35 + 33

x = 68

hope it helps!
