Direct variation is y=kx, inverse variation is y=k/x....
-5y=-2x divide both sides by -5
y=2.5x
So this is a direct variation with a constant of 2.5
Let one no. be x.
then another no. = (19-x).
x - (19 - x ) = 55
2 x - 19 = 55
x = 37
another no. = 19 - 37 = -18
Can you follow me and like me please? I hope i can help you more.☺
