y = x+7
\n" ); document.write( "x2 + y2 =29
\n" ); document.write( "---------------
\n" ); document.write( "Do you mean 2x + 2y = 29?
\n" ); document.write( "If so,
\n" ); document.write( "Sub for y in the 2nd eqn
\n" ); document.write( "2x + 2(x+7) = 29
\n" ); document.write( "2x + 2x + 14 = 29
\n" ); document.write( "4x = 15
\n" ); document.write( "x = 15/4, or 3.75
\n" ); document.write( "y = 10.75
