Let the multiplicative factor be x
\n" ); document.write( "Then number of boys and girls are 7x, and 9x, respectively
\n" ); document.write( "As given, 7x = 9x - 12
\n" ); document.write( "7x - 9x = - 12
\n" ); document.write( "- 2x = - 12
\n" ); document.write( "\"matrix%281%2C5%2C+x%2C+%22=%22%2C+%28-+12%29%2F%28-+2%29%2C+%22=%22%2C+6%29\"
