Let s = the smaller number
\n" ); document.write( "Let g = the greater number
\n" ); document.write( "g = 3s - 7
\n" ); document.write( "s + g = 13
\n" ); document.write( "solve for g by adding -s to each side
\n" ); document.write( " g = 13 - s
\n" ); document.write( "Substitute (13 - s) for g in g = 3s - 7
\n" ); document.write( "(13 - s) = 3s - 7
\n" ); document.write( "add s to each side
\n" ); document.write( " 13 = 4s - 7
\n" ); document.write( "add 7 to each side
\n" ); document.write( " 20 = 4s
\n" ); document.write( "divide each side by 4
\n" ); document.write( " 5 = s
\n" ); document.write( "Since g = 3s - 7, g = 3(5) - 7
\n" ); document.write( "g = 15 - 7
\n" ); document.write( "g = 8
\n" ); document.write( "So the numbers are 5 and 8 .
\n" ); document.write( "
\n" ); document.write( "
\n" );
