32 = x - 5

37

100

5 + x = x + 5

5 = 5 or x = x

5x = 5x + 3 

0  ≠ 3

200

5x = 65

13

200

5x + 3 = 5x + 3

3 = 3 or 5x = 5x

200

5x - 3 = 5x + 3

-3 ≠ 3

300
39 = 5x + 4

7

300

7(x + 2) = 7x + 14

14 = 14 or 7x = 7x

300

44 + 8x = 8(x + 5)

44 ≠ 40

400

15 = 5x/7

21

3(x+1) -5 = 3x - 2

-2 = -2 or 3x = 3x

8 - 7(4v + 5) = -27 -28v



-27 = -27 or -28v = -28v
