Let
\n" ); document.write( "Total number of Boys = b
\n" ); document.write( "Total number of Girls = g
\n" ); document.write( "the number of boys is 16 less than twice the number of girls
\n" ); document.write( "b=2g-16........(1)
\n" ); document.write( "There are 68 students altogether
\n" ); document.write( "b + g = 68
\n" ); document.write( "g = 68 - b
\n" ); document.write( "Put the value of b in above equation
\n" ); document.write( "g = 68 - (2g-16)
\n" ); document.write( "g = 68 - 2g + 16
\n" ); document.write( "g + 2g = 68 + 16
\n" ); document.write( "3g = 84
\n" ); document.write( "g = 84/3
\n" ); document.write( "g = 28
\n" ); document.write( "There are 28 girls in grade eight
\n" ); document.write( "And
\n" ); document.write( "Boys = Total sutudents - Grils
\n" ); document.write( "Boys = 68 - 28
\n" ); document.write( "Boys = 40\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
