\n" ); document.write( "The given function is
\n" ); document.write( "f(x,y) = 5y+10x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We want to find f(6,2)
\n" ); document.write( "Wherever you see 'x', replace it with 6.
\n" ); document.write( "Wherever you see 'y', replace it with 2.
\n" ); document.write( "Then simplify.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "f(x,y) = 5y+10x
\n" ); document.write( "f(6,y) = 5y+10*6 ...... replace x with 6
\n" ); document.write( "f(6,2) = 5*2+10*6 ...... replace y with 2
\n" ); document.write( "f(6,2) = 10+60
\n" ); document.write( "f(6,2) = 70\r
\n" ); document.write( "
\n" ); document.write( "
