How do I solve this?
\n" ); document.write( "x^2+y^2=25
\n" ); document.write( "x+2y=-1
\n" ); document.write( "-----------
\n" ); document.write( "I would use substitution.
\n" ); document.write( "x = -2y - 1
\n" ); document.write( "Sub for x in the 1st eqn, solve for y.
\n" ); document.write( "You'll get 2 values for y.
\n" ); document.write( "Sub those into the line eqn, not the circle, and find the values for x.
\n" ); document.write( "
\n" ); document.write( "
\n" );
