4x+3y=7
\n" ); document.write( "2x-y=1
\n" ); document.write( "-----------
\n" ); document.write( "Solve 2nd for \"y\":
\n" ); document.write( "y = 2x-1
\n" ); document.write( "----
\n" ); document.write( "Substitute for \"y\" in 1st and solve for \"x\":
\n" ); document.write( "4x+3(2x-1) = 7
\n" ); document.write( "4x+6x-3 = 7
\n" ); document.write( "10x = 10
\n" ); document.write( "x = 1
\n" ); document.write( "-------
\n" ); document.write( "Substitute into y = 2x-1 to solve for \"y\":
\n" ); document.write( "y = 2*1-1 = 1
\n" ); document.write( "=================
