Question

5x+2y=p and 10x+4y=3 ?​

Answer 1

Answer:

1.5

Step-by-step explanation:

multiply by 2 =) 2 (5x +2 y = p )

=) 10x +4y =2p

by elimination method ;

0 = 2p - 3

2p = 3

p = 3/2

p = 1.5

Answer 2

Answer:

Here , a1=5, b1=2, c1=(-p), a2=10, b2=4 and c2=(-3)

As, a1/a2=b1/b2 but is not=c1/c2

Therefore, the given pair of equations have no solution.

Hope you have got your answer.
