Pleas answer quick!! Which procedure justifies whether -3x(5-4)+3(x-6) is equivalent to -12x-6? 1. The expressions are not equivalent because - 3(2)(5-4)+3(2-6)=-18 and -12(2)-6=-30 2.The expressions are not equivalent because -3(2)(5-4)+3(2-6)=-18 and -12(3)-6=-42
3. The expressions are equivalent because -3(2)(5-4)+312-6) = -18 and -12(-2)-6 = 18
4. The expressions are equivalent because -3(2)(5-4) + 3(2-6)=-18 and -12(1)-6=-18
