x+y = -12.43
\n" ); document.write( "...
\n" ); document.write( "x-y = 117.77
\n" ); document.write( "..
\n" ); document.write( "add the two equations
\n" ); document.write( "2x=105.34
\n" ); document.write( "/2
\n" ); document.write( "x=52.67
\n" ); document.write( "...
\n" ); document.write( "plug value of x in first equation
\n" ); document.write( "52.67+y=-12.43
\n" ); document.write( "-52.67
\n" ); document.write( "y=-12.43-52.67
\n" ); document.write( "y = -65.10
