\n" ); document.write( "To start with, put both equations in the form Ax+By=C and simplify.

\n" ); document.write( "8x + 64 = 8y
\n" ); document.write( "8x - 8y = -64
\n" ); document.write( "x - y = -8

\n" ); document.write( "-4x + 4y = 32
\n" ); document.write( "x - y = -8

\n" ); document.write( "The two equations are equivalent; any solution to one equation is a solution to the other. There is no unique (x,y) solution.

\n" ); document.write( "If you want a solution in (x,y) form, then solve the equation for y in terms of x and write the solution parametrically:

\n" ); document.write( "x - y = -8
\n" ); document.write( "y = x+8

\n" ); document.write( "Solution: (x,x+8) where x is any number

\n" ); document.write( " \n" ); document.write( "
\n" );
