1. x+2 = 3
x = 3 -2
x = 1

2.21 = x+3
21-3 = x
x = 18

3. x-1 = 12
x = 12+1
x = 13

4. x-5 = 6
x = 6+5
x = 11

5. 3x = 36
x = 36/3
x = 12

6. 8x = 64
x = 64/8
x = 8

7. a+2 = a+1+üçgen
üçgen = a-a+2-1
üçgen = 1

8. x-12=-4+x+o
o = x-12+4-x
o = -8

9. 2(x+1) = 8
x+1 = 8/2
x+1 = 4
x = 4-1
x = 3

10. 3(x-2) = 18
x-2 = 18/3
x-2 = 6
x = 6+2
x = 8

11. x/3 = 12
x = 12.3
x = 36

12. 4(x-1) = 16
x-1 = 16/4
x-1 = 4
x = 4+1
x = 5
