Let x=smaller number
\n" ); document.write( "Then x+12=the larger number
\n" ); document.write( "2(x+12)=twice the larger number\r
\n" ); document.write( "\n" ); document.write( "Now we are told that:\r
\n" ); document.write( "\n" ); document.write( "x+2(x+12)=39 get rid of parens
\n" ); document.write( "x+2x+24=39 subtract 24 from both sides
\n" ); document.write( "x+2x+24-24=39-24 collect like terms
\n" ); document.write( "3x=15 divide both sides by 3
\n" ); document.write( "x=5 -------------------------------smaller number\r
\n" ); document.write( "\n" ); document.write( "x+12=5+12=17----------------------------larger number\r
\n" ); document.write( "\n" ); document.write( "CK\r
\n" ); document.write( "\n" ); document.write( "5+2(17)=39
\n" ); document.write( "5+34=39
\n" ); document.write( "39=39\r
\n" ); document.write( "\n" ); document.write( "5+12=17
\n" ); document.write( "17=17\r
