Question

if (3,-p) is solution of 5x-2 y=19 find value of p​

Answer 1

Answer:

0.5

Step-by-step explanation:

let x=3 and y=-p

5x-2y=19 is the given equation

substitute the x and y values in the given equation

5(3)-2(-p)=19

18+2p=19

2p=19-18

2p=1

p=1/2

p=0.5

Answer 2

Answer:

5x-2y=19

put,x=3 and y=-p

5(3)-2(-p)=19

15+2p=19

2p=19-15

2p=4

p=4/2

p=2

Hence,The value of p is,2.
