let f = the first number, and s = the 2nd number.
\n" ); document.write( "f + 2s = 22,
\n" ); document.write( "2f + s = 23.
\n" ); document.write( "From the first equation, f = 22-2s. Substitute into the 2nd equation:
\n" ); document.write( "2(22-2s) + s = 23,
\n" ); document.write( "44 - 4s +s = 23,
\n" ); document.write( "-3s = -21,
\n" ); document.write( "s = 7, the second number.
\n" ); document.write( "f = 22-2s = 22 - 14 = 8, the first number.
\n" ); document.write( "
\n" );
