Let the first number be n.\r
\n" ); document.write( "\n" ); document.write( "Let the second number be n + 40.\r
\n" ); document.write( "\n" ); document.write( "n + (n + 40) = 180\r
\n" ); document.write( "\n" ); document.write( "n + n + 40 = 180\r
\n" ); document.write( "\n" ); document.write( "2n + 40 = 180\r
\n" ); document.write( "\n" ); document.write( "Subtract 40 from each side of the equation.\r
\n" ); document.write( "\n" ); document.write( "2n + 40 - 40 = 180 -40\r
\n" ); document.write( "\n" ); document.write( "Combine like terms:\r
\n" ); document.write( "\n" ); document.write( "40 - 40 = 0\r
\n" ); document.write( "\n" ); document.write( "180 - 40 = 140\r
\n" ); document.write( "\n" ); document.write( "2n = 140\r
\n" ); document.write( "\n" ); document.write( "Divide each side by 2\r
\n" ); document.write( "\n" ); document.write( "2n/2 = 140/2\r
\n" ); document.write( "\n" ); document.write( "n = 70\r
\n" ); document.write( "\n" ); document.write( "n + 40 = 70 + 40 = 110\r
\n" ); document.write( "\n" ); document.write( "The two numbers are:\r
\n" ); document.write( "\n" ); document.write( "70 and 110 \n" ); document.write( "

\n" );
