-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 -

    There's a minus sign in front of the quantity in parentheses

    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.
