document.write( "using substitution
\n" );
document.write( "y=2x-9
\n" );
document.write( "x+3y=8
\n" );
document.write( "substituting (2x-9) for y
\n" );
document.write( "x +3(2x-9) = 8
\n" );
document.write( " 7x = 35
\n" );
document.write( "  x = 5
\n" );
document.write( "  y = 1   |y=2x-9 = 2*5 - 9 = 1
\n" );
document.write( " One solution (1,5)
