First order of business, put all the x's and y's to one side:
\n" ); document.write( "2x - 2y =3+x
\n" ); document.write( "x = 3y + 4
\n" ); document.write( ".
\n" ); document.write( "Rearranging then, we have:
\n" ); document.write( "x - 2y =3
\n" ); document.write( "x - 3y =4
\n" ); document.write( ".
\n" ); document.write( "Now, using the \"elimination method\", subtract the second equation from the first:
\n" ); document.write( " x - 2y = 3
\n" ); document.write( "-x + 3y = -4
\n" ); document.write( "---------------
\n" ); document.write( " y = -1
\n" ); document.write( ".
\n" ); document.write( "Now, use the above definition of 'y' and substitute it into equation 2:
\n" ); document.write( "x = 3y + 4
\n" ); document.write( "x = 3(-1) + 4
\n" ); document.write( "x = -3 + 4
\n" ); document.write( "x = 1
\n" ); document.write( ".
\n" ); document.write( "Solution:
\n" ); document.write( "(x,y) = (1, -1)
\n" ); document.write( " \n" ); document.write( "
\n" );
