11. In Triangle ABC, D and E are points on AB and AC respectively such that DE || BC. If AD = 6x - 7, DB = 4x - 3, AE = 3x - 3 and EC = 2x-1, find x

Select the correct answer from the drop-down menu. subtracting 3xy^2 from 8xy^2 gives the same result as the expression. [tex]3xy ^{2} - 8xy ^{2} [/tex][tex] { - 7xy}^{2} - {2xy}^{2} [/tex][tex] {7xy}^{2} - {2xy}^{2} [/tex]
