Question

find a value of p for which x=-2y, y=-1 is a solution of the linear equation 5x+22py=2p

Answer 1

HEY
HERE IS YOUR ANSWER
______________________________

x=-2y
y=-1

Now,

5x+22py=2p

5×(-2y)+22py=2p

-10y+22py=2p

-10×-1 + 22×-1 p =2p

10-22p=2p

10=2p+22p

24p=10

p=10/24

p=5/12

Answer 2

$5( - 2y) + 22p( - 1) - 2p = 0 \\ 5( - 2 \times - 1) - 22p - 2p = 0 \\ 10 - 22p - 2p = 0 \\ 10 - 24p = 0$
