x +y = 15 (the sum of two numbers is 15.
\n" ); document.write( "3x = 5y-11 ( three times one of the numbers is 11 less than five times the other).\r
\n" ); document.write( "\n" ); document.write( "Multiply the first equation by -3.\r
\n" ); document.write( "\n" ); document.write( "-3x - 3y = -45.
\n" ); document.write( "Rewrite the second equation as \r
\n" ); document.write( "\n" ); document.write( "3x - 5y = -11.\r
\n" ); document.write( "\n" ); document.write( "Add these two equations:\r
\n" ); document.write( "\n" ); document.write( "-8y = -56
\n" ); document.write( "Divide both sides by -8.
\n" ); document.write( "y = 7.
\n" ); document.write( "Now, plug in this value in the first equation(x+y=15).\r
\n" ); document.write( "\n" ); document.write( "x + 7 = 15.
\n" ); document.write( "x = 8
\n" ); document.write( "Therefore the two numbers are 7 and 8.
\n" ); document.write( " \n" ); document.write( "
\n" );
