You can put this solution on YOUR website!
I'm assuming this is a system of equations and you're looking for the intersection??
\n" ); document.write( "1. $\"2x%5E2+-+8y%5E3+=+19\"$
\n" ); document.write( "2. $\"4x%5E2+%2B+16y%5E3+=+34\"$
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( ".
\n" ); document.write( "Multiply eq. 1 by 2 and add the equations together to eliminate the $\"y%5E3\"$ term.
\n" ); document.write( " $\"4x%5E2-16y%5E3%2B4x%5E2%2B16y%5E3=38%2B34\"$
\n" ); document.write( " $\"8x%5E2=72\"$
\n" ); document.write( " $\"x%5E2=9\"$
\n" ); document.write( " $\"highlight%28x=0+%2B-+3%29\"$
\n" ); document.write( "Then use either equation to solve for $\"y\"$ .
\n" ); document.write( "When $\"x=3\"$ ,
\n" ); document.write( " $\"2%289%29-8y%5E3=19\"$
\n" ); document.write( " $\"18-8y%5E3=19\"$
\n" ); document.write( " $\"-8y%5E3=1\"$
\n" ); document.write( " $\"y%5E3=-1%2F8\"$
\n" ); document.write( " $\"highlight%28y=-1%2F2%29\"$
\n" ); document.write( "The $\"y\"$ solution is identical for $\"x=-3\"$ .
