Question

find the value of p for which X=-2 Y=-1 is a solution of linear equation 5 x + 2 p y equal to 2​

Answer 1

Heya ❤️

here's your answer !!

5x+2py=2

put x=-2 and y=-1

5×-2+2p×-1=2

-10-2p=2

-2p=2+10

-2p=12

p=12/-2

p=-6 (required answer)

Hope it helps !!

Answer 2

$5x + 2py = 2 \\ \\ put \: the \: value \: of \: \\ x = - 2 \\y = - 1 \\ \\ 5( - 2) + 2(p)( - 1) = 2 \\ \\(- 10) + ( - 2p) = 2 \\ \\ - 10 - 2p = 2 \\ \\ - 2p = 12 \\ \\ 2p = - 12 \\ \\ p = - 12 \div 2 \\ \\ p = - 6$
