Starting with:
\n" ); document.write( "5x-y=13
\n" ); document.write( "x+2y=1
\n" ); document.write( ".
\n" ); document.write( "Multiply both sides of the top equation by 2:
\n" ); document.write( "10x-2y=26
\n" ); document.write( "x+2y=1
\n" ); document.write( ".
\n" ); document.write( "Add the two equations together:
\n" ); document.write( "10x-2y=26
\n" ); document.write( " x+2y=1
\n" ); document.write( "-----------
\n" ); document.write( "11x =27
\n" ); document.write( "x = 27/11
\n" ); document.write( ".
\n" ); document.write( "Plug the above into:
\n" ); document.write( "x+2y=1
\n" ); document.write( "27/11+2y=1
\n" ); document.write( "Solve for y:
\n" ); document.write( "27+22y=11
\n" ); document.write( "22y = -16
\n" ); document.write( "y = -16/22
\n" ); document.write( "y = -8/11
\n" ); document.write( ".
\n" ); document.write( "Solution:
\n" ); document.write( "x = 27/11
\n" ); document.write( "y = -8/11\r
\n" ); document.write( "
