Parentheses can be eliminated using the distributive property
-6x +6(3x -4xy) = -6x +18x -24xy
Like terms (those with the variable x only) can be combined
x(-6+18) -24xy = 12x -24xy . . . . . simplified
_____
In some cases, you may be interested in factoring the expression. 12x is a common factor for the two terms, so another way to write this expression is
... 12x(1 -2y)
