-9x-33=6(x+7)
-9x-33 = 6x + 42
-9x +9x -33 = 6x +9x + 42
-33 = 15x + 42
-33 - 42 = 15x + 42 - 42
-75 = 15x
-75/15 = 15x/15
-5 = x
i ill feel SO stupd if i get this wrong but watever

so u have -9x - 33 = 6 (x +7)
notice that all of the numbers can be invisble by 3.....so divide by 3 and u get this:
-3x - 11 = 2(x+7)
then distribute
-3x - 11 = 3x + 14
then combine like terms
-25 = 5x
divide by 5 and u get
x = -5
