4x-y=-10
\n" ); document.write( "2x+3y=-3
\n" ); document.write( "----
\n" ); document.write( "Modify for elimination::
\n" ); document.write( "4x - y = -10
\n" ); document.write( "4x +6y = -6
\n" ); document.write( "------------------
\n" ); document.write( "Subtract and solve for \"y\"::
\n" ); document.write( "7y = 4
\n" ); document.write( "y = 4/7
\n" ); document.write( "------
\n" ); document.write( "Solve for \"x\"::
\n" ); document.write( "4x - y = -10
\n" ); document.write( "4x - (4/7) = -(70/7)
\n" ); document.write( "4x = -66/7
\n" ); document.write( "x = -33/14
