**Ms. Sue**, Sunday, August 25, 2013 at 7:33pm-5x - 10 = 2 - (x + 4)

-4x = 12 - 4

-4x = 8

x = -2

**Cassidy**, Sunday, August 25, 2013 at 7:37pmThx Ms.Sue! But why the +4 became -4? I confused with this part

- 8th Math -
**Ms. Sue**, Sunday, August 25, 2013 at 7:40pmThere's a minus sign in front of the quantity in parentheses

2 - (x + 4)

A + and a - is always a minus.

**Cassidy**, Sunday, August 25, 2013 at 7:58pmwhat if there's a sign of positive in front of the quantity in parenthese, such like 2+(x+4)....which mean the +4 will be staying the same as +4?
