Question

If AB=x+3,BC=2x, 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

Answer 2

Answer:

The value of x is 8

Step-by-step explanation:

Step 1:

Given Data

AB = x + 3,

BC = 2x,  

AC = 4x - 5,

If B lies on AC

So, AB + BC = AC  

Step 2:  

x + 3 + 2x = 4x - 5

3x + 3 = 4x – 5

Step 3:  

3x - 4x = - 5 - 3

- x = - 8

x = 8
