sol:
\n" ); document.write( "let us take k=x
\n" ); document.write( "substitute this value in y=kz
\n" ); document.write( "y=xz
\n" ); document.write( "substitute the values x=2 and y=6 in y=xz
\n" ); document.write( "6=2*z
\n" ); document.write( "dividing by 2 on both sides
\n" ); document.write( "6/2=2*z/2
\n" ); document.write( "3=z
\n" ); document.write( "substitute these values in y=kz
\n" ); document.write( "6=k*3
\n" ); document.write( "dividing by 3 on both sides
\n" ); document.write( "6/3=k*3/3
\n" ); document.write( "k=2
\n" ); document.write( "equation y=2z
\n" ); document.write( "when x=4
\n" ); document.write( "y=xz
\n" ); document.write( "y=4*z
\n" ); document.write( "6=4z
\n" ); document.write( "dividing by 4 on both sides
\n" ); document.write( "6/4=4z/4
\n" ); document.write( "3/2=z
\n" ); document.write( "y=xz
\n" ); document.write( "y=4*3/2
\n" ); document.write( "y=6\r
