If -5x – 1 = -11, then -5x = -10:

If -5x – 1 = -11, then -5x = -10

5.

If 10a = 2b and 2b = c, then 10a = c:

If 10a = 2b and 2b = c, then 10a = c

6.

-7(x – 4) = -7x + 28:

-7(x – 4) = -7x + 28

7.

If 6y = 24, then 6y – 3 = 24 – 3:

If 6y = 24, then 6y – 3 = 24 – 3

8.

If 10x + w = 41 and w = 1, then 10x + 1 = 41:

If 10x + w = 41 and w = 1, then 10x + 1 = 41

9.

If y/2 = -10, then y = -20:

If y/2 = -10, then y = -20

10.

If 3x = 2y and 2y = z, then 3x = z:

If 3x = 2y and 2y = z, then 3x = z
