Let x= age of youngest
\n" ); document.write( "Then 3x=age of oldest
\n" ); document.write( "And 3x-2=age of next to oldest
\n" ); document.write( "And 2x=age of middle sis
\n" ); document.write( "And x+3=age of remaining sis\r
\n" ); document.write( "\n" ); document.write( "And all this adds up to 211. So our equation to solve is:\r
\n" ); document.write( "\n" ); document.write( "x+3x+3x-2+2x+x+3=211 collect like terms\r
\n" ); document.write( "\n" ); document.write( "10x+1=211 subtract 1 from both sides
\n" ); document.write( "10x+1-1=211-1
\n" ); document.write( "10x=210
\n" ); document.write( "x=21 ---------------youngest
\n" ); document.write( "3x=3*21=63-------------oldest
\n" ); document.write( "3x-2=63-2=61------------------next oldest
\n" ); document.write( "2x=2*21=42---------------------middle
\n" ); document.write( "x+3=21+3=24--------------------remaining\r
\n" ); document.write( "\n" ); document.write( "CK\r
\n" ); document.write( "\n" ); document.write( "21+63+61+42+24=211
\n" ); document.write( "211=211\r
