Question

If 2x+py = -5 and 3x + 3y = 6 has a unique solution, then find the value of 'p'.​

Answer 1

Answer:

p =2

Step-by-step explanation:

2x +py =-5

3x+3y=6

unique solution that means intersecting lines

A1/A2 not equal to B1/B2

2/3 not equal to p/3

cross multiply the 2/3 and p/3

p=2

Answer 2

Step-by-step explanation:

Given:

2x+py=-5

3x+3y=6

To have unique solutions, the condition is

a1/a2=b1/b2

=²/3=p/3

=3p=6

P=6/3

p=2
