\n" ); document.write( "\n" ); document.write( "one number is 3 less than a second number. twice the second number is 3 less than 3 times the first. find the two numbers\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "The second number is obviously the larger number, and will be named L
\n" ); document.write( "The other number will be the smaller and named S\r
\n" ); document.write( "\n" ); document.write( "Since the smaller number, or S is 3 less than the larger, then we can say that S = L – 3 ___ S – L = - 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Also, since twice the second number (larger number) is 3 less than 3 times the other number (smaller number), we can say that: 2L = 3S – 3 ______ - 3S + 2L = - 3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "We now have the following simultaneous equations:\r
\n" ); document.write( "\n" ); document.write( " S – L = - 3 -------- eq (i)
\n" ); document.write( "– 3S + 2L = - 3 ----- eq (ii)
\n" ); document.write( " 2S – 2L = - 6 -------- eq (iii) ----- multiplying eq (i) by 2
\n" ); document.write( " – S = - 9 ------ Adding eq (ii) and eq (iii)
\n" ); document.write( "S, or smaller number = \"%28-9%29%2F-1\" = \"highlight_green%289%29\" \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Substituting 9 for S in eq (i) gives us:
\n" ); document.write( "9 - L = - 3
\n" ); document.write( "- L = - 12\r
\n" ); document.write( "\n" ); document.write( "L, or larger number = \"%28-12%29%2F-1\" = \"highlight_green%2812%29\" \r

\n" ); document.write( "-----------
\n" ); document.write( "Smaller #: 9
\n" ); document.write( "Larger #: 12\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Smaller # (9) is 3 less than larger # (12)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Twice larger # (12) = 2(12) = 24
\n" ); document.write( "Thrice smaller # (9) = 3(9) = 27 \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Twice larger # (24) is 3 less than thrice smaller # (27)\r
