If \((h,k)\) is the point to which the origin has to be shifted by translation of axes to remove the terms containing \(x\) and \(y\) from the equation
\[
2x^2+3xy+y^2+4x-8y+5=0
\]
then \(2h+k=\)
Show Hint
For translation of axes problems, first compare with standard second degree equation and use simultaneous equations formed by eliminating linear terms. This method is faster than direct substitution.
