There are 3 sides to a triangle and 4 sides to a rectangle.
\n" ); document.write( "Let g = number of girls
\n" ); document.write( "and b = number of boys
\n" ); document.write( "then since we have two variables, we'll need two equations.
\n" ); document.write( ".
\n" ); document.write( "g + b = 26 (equation 1)
\n" ); document.write( "3g + 4b = 92 (equation 2)
\n" ); document.write( ".
\n" ); document.write( "solving equation 1 for g, we get:
\n" ); document.write( "g = 26-b
\n" ); document.write( ".
\n" ); document.write( "Substituting the above into equation 2 we can then solve for b:
\n" ); document.write( "3g + 4b = 92
\n" ); document.write( "3(26-b) + 4b = 92
\n" ); document.write( "78 - 3b + 4b = 92
\n" ); document.write( "78 + b = 92
\n" ); document.write( "b = 14 (number of boys)
\n" ); document.write( ".
\n" ); document.write( "Substitute the above into equation 1 and solve for g:
\n" ); document.write( "g + b = 26
\n" ); document.write( "g + 14 = 26
\n" ); document.write( "g = 12 (number of girls)
\n" ); document.write( "
\n" );
