sol:px+3y+9---------------(1)st equation
\n" ); document.write( " 7x-11y+5---------------(2) equation
\n" ); document.write( "these two equations are on left hand side
\n" ); document.write( "first adding these two equations
\n" ); document.write( "
\n" ); document.write( " =(px+7x)+(3y-11y)+(9+5)
\n" ); document.write( " =(p+7)x+(3-11)y+(14)
\n" ); document.write( " =(p+7)x+(-8)y+(14)
\n" ); document.write( " =(p+7)x-8y+14 (i.e;(+)(*)(-)=-)
\n" ); document.write( " now take right hand side equation
\n" ); document.write( " 3x-qy+14
\n" ); document.write( "now equating left and right handside equations
\n" ); document.write( "(p+7)x-8y+14 = 3x-qy+14
\n" ); document.write( "comparing x coficient and y coficients on both sides
\n" ); document.write( "here p+7 is lefthandside x coficient and 3 is righthandside coficient
\n" ); document.write( "p+7=3
\n" ); document.write( "p=3-7=-4;
\n" ); document.write( "comparing y coficients on both sides
\n" ); document.write( "-8=-q
\n" ); document.write( "q=8
\n" ); document.write( "answer is p=-4,q=8 \n" ); document.write( "
\n" );
