-5x-10 = 2-(x+4)

• 8th Math -

-5x - 10 = 2 - (x + 4)

-4x = 12 - 4

-4x = 8

x = -2

Thx Ms.Sue! But why the +4 became -4? I confused with this part

• 8th Math -

2 - (x + 4)

A + and a - is always a minus.

• 8th Math -

what 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?

Yes.
