You can put this solution on YOUR website!
Chaundra = x
\n" ); document.write( "Chaundra's younger brother = x - 2
\n" ); document.write( "Chaundra's older sister = x + 4
\n" ); document.write( "Chaundra's mother = 41
\n" ); document.write( "Chaundra's father = 41
\n" ); document.write( "all 5 of them together = 123\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Chaundra + brother + sister + mother + father = 123\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x + x-2 + x+4 + 41 + 41 = 123 | re-arranging
\n" ); document.write( "3x + 84 = 123 | - 84 on both sides
\n" ); document.write( "3x = 39 | ÷ 3 on both sides
\n" ); document.write( "x = 13 → Chaundra's age\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "You can substitute x by 13 to check if your solution is correct (if the result really is 123):\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "13 + 13-2 + 13+4 + 41 + 41 = 123 → true \n" ); document.write( "

\n" );
