Solve by using substitution.
\n" ); document.write( "2x = y - 4
\n" ); document.write( "-3y = x - 5
\n" ); document.write( "--------
\n" ); document.write( "Rearrange::
\n" ); document.write( "2x - y = -4
\n" ); document.write( "x +3y = 5
\n" ); document.write( "------
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "2x - y = -4
\n" ); document.write( "2x + 6y = 10
\n" ); document.write( "----------------
\n" ); document.write( "Subtract and solve for \"y\"::
\n" ); document.write( "7y = 14
\n" ); document.write( "y = 2
\n" ); document.write( "-----
\n" ); document.write( "Solve for \"x\"::
\n" ); document.write( "x = -3y+5
\n" ); document.write( "x = -6+5 = -1
\n" ); document.write( "----------------
