2x + 9y = 0
\n" ); document.write( "3x + 5y = 17
\n" ); document.write( ".
\n" ); document.write( "multiply the first equation by 3 and the second by 2; then subtract
\n" ); document.write( ".
\n" ); document.write( "6x + 27y = 0
\n" ); document.write( "6x + 10y = 34
\n" ); document.write( "--------------
\n" ); document.write( "17y = -34
\n" ); document.write( ".
\n" ); document.write( "y = -2
\n" ); document.write( ".
\n" ); document.write( "substitute to find 'x'
\n" ); document.write( ".
\n" ); document.write( "2x + 9(-2) = 0
\n" ); document.write( "2x -18 = 0
\n" ); document.write( "2x = 18
\n" ); document.write( "x = 9
\n" ); document.write( ".
\n" ); document.write( "check by substituting these values into the other equation
\n" ); document.write( ".
\n" ); document.write( "3(9) + 5(-2) = 17 ??
\n" ); document.write( "27 -10 = 17
\n" ); document.write( "correct
\n" ); document.write( ".
\n" ); document.write( "Answer: (9,-2)
\n" ); document.write( ".
\n" ); document.write( "Done. \n" ); document.write( "
