**Steve**, Tuesday, August 20, 2013 at 12:16amforget all the extra minus signs, and just follow the usual steps:

-3-3x = -9

add 3 to get the x's on one side

-3-3x+3 = -9+3

-3x = -6

now divide by the coefficient of x:

-3x/-3 = -6/-3

x = 2

Or, you could have just multiplied everything by -1 to start with:

-3-3x = -9

3+3x = 9
