Which procedure justifies whether -3x(5-4)+3(x-6) is equivalent to -12x-6?
The expressions are not equivalent because -3(2)(5-4) +3(2-6)=-18 and -12(2)-6--30
The expressions are not equivalent because -3(2)(5-4)+ 3(2-6) --18 and -12(3)-6=-42
The expressions are equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(-2)-6-18
The expressions are equivalent because -3(2)(5-4)+ 3(2-6)=-18 and -12(1)-6--18
