solve the system of linear equations using substitution:
\n" ); document.write( "y=2x
\n" ); document.write( "y=-4x+8
\n" ); document.write( "----------
\n" ); document.write( "Since they both equal y, sub for y in either equation.
\n" ); document.write( "2x = -4x + 8
\n" ); document.write( "6x = 8
\n" ); document.write( "x = 4/3
\n" ); document.write( "y = 8/3
\n" ); document.write( "
\n" );
