-5 + w/3 = -1

w/3 = -1 + 5

w/3 = 4

w = 4 * 3

w = 12

w/3 = -1 + 5

w/3 = 4

w = 4 * 3

w = 12

1 Answer/Comment

24 - 3x = -27

-3x + 24 = - 27

-3x = -27 - 24

-3x = -51

x = -51/-3

x = 17

-3x + 24 = - 27

-3x = -27 - 24

-3x = -51

x = -51/-3

x = 17

x - (-17) = x + 17 does not mean the same as the other three.

x - 17 = x - 17

x + (-17) = x - 17

x - (-17) = x + 17

- 17 + x = x - 17

x - 17 = x - 17

x + (-17) = x - 17

x - (-17) = x + 17

- 17 + x = x - 17
