Hi, there--
\n" ); document.write( ".
\n" ); document.write( "Let g be the number of girls in the class.
\n" ); document.write( ".
\n" ); document.write( "\"two less than three times the number of girls\" translate to the algebraic expression \"3g-2\".
\n" ); document.write( ".
\n" ); document.write( "The total number of girls and boys is 18, so we write that as an equation.
\n" ); document.write( "\"g%2B3g-2=18\"
\n" ); document.write( ".
\n" ); document.write( "Now we combine like terms and solve for g.
\n" ); document.write( "\"4g-2=18\"
\n" ); document.write( ".
\n" ); document.write( "Add 2 to both sides of the equation.
\n" ); document.write( "\"4g=20\"
\n" ); document.write( ".
\n" ); document.write( "Divide both sides by 4.
\n" ); document.write( "\"g=5\"
\n" ); document.write( ".
\n" ); document.write( "According to the algebra, there are 5 girls (g=5). Since there are 3g-2 boys, there are 3(5)-2)=13 boys.
\n" ); document.write( ".
\n" ); document.write( "CHECK:
\n" ); document.write( "Are there 18 students in the class? 5+13=18...YES!
\n" ); document.write( "Is the number of boys two less than three times the number of girls? Three times five is fifteen; two less than fifteen is thirteen...YES!
\n" ); document.write( ".
\n" ); document.write( "That's it. Feel free to email if you still have Qs about this.
