You can put this solution on YOUR website!
To use the elimination method, add the two equations togehter:
\n" ); document.write( " 5x+6y=-13
\n" ); document.write( "+ 8x-6y=-52
\n" ); document.write( " ---------
\n" ); document.write( " 13x=-65
\n" ); document.write( "Solve for x:
\n" ); document.write( "\"highlight%28x=-5%29\"
\n" ); document.write( "Plug this value in to either of the equations and get y:
\n" ); document.write( "\"5%28-5%29%2B6y=-13\"
\n" ); document.write( "\"-25%2B6y=-13\"
\n" ); document.write( "\"6y=12\"
\n" ); document.write( "\"highlight%28y=2%29\"
\n" ); document.write( "================
