Two points D and E lie on sides AB and AC respectively of ΔABC. Give the information that DE|| BC is not true through the values given in the following questions:

AB = 5.6 cm, AD = 1.4 cm, AC = 9.0 cm and AE = 1.8 cm.

Point D and E lie on the sides AB and AC respectively of ΔABC such that DE|| BC. Then,

If AD = 4x – 3, AE = 8x – 7, BD = 3x – 1 and CE = 5x – 3, then find the value of x.
