If the lines (3 x+4 y-5=0,2 x+3 y-4=0 ) and (p x+4 y-6=0 ) all meet at the same point, then (p ) is equal to
Options
- A-2
- B0
- C1
- D2
Correct answer
D. 2
Step-by-step solution
( aligned 3 x+4 y-5 & =0 (i) 2 x+3 y-4 & =0 (ii) and p x+4 y-6 & =0 (iii) aligned ) From Eqs. (i) and (ii), we get (x=-1, y=2 ) So, ( -p+8-6=0 p=2 )
