Question

Find the value of p if the lines represended by 3x-y+5=0and6x-2y-p=0 are parallsl rsperensted by

Answer 1

Answer:

if lines are parallel then the equation has no solution. it is inconsistence eqution

3x-y+5= 0--------1

6x-2y-p=0 ---------2

Solving by substitution method

3x-y+5 =0

3x= y-5

x= y-5/3 --------3

substitute value of x in eq. 2

6(y-5/3)-2y-p= 0

2y-10-2y= p

0-10= p

-10= p
