Question

if AB=x+3,BC=2x and AC=4x-5 then for what value of 'x', B lies on AC

Answer 1

Solution:-

If B lies on AC

So, AB + BC = AC

x + 3 + 2x = 4x - 5

3x + 3 = 4x - 5

3x - 4x = - 5 - 3

- x = - 8

x = 8 ANswer

4.4

Answer 2

Answer:

assuming that A, B and C are colinear x= -2

Step-by-step explanation:

AB + BC = AC

x+3 + 2 x = 4x-5

3x +3= 4x-5

-x = -8

therefore x = 8
