a = 2g-6,
\n" ); document.write( "5a = 8g.
\n" ); document.write( "Then, by substitution, 5(2g-6) = 8g,
\n" ); document.write( "10g-30 = 8g,
\n" ); document.write( "10g-8g = 30,
\n" ); document.write( "2g = 30,
\n" ); document.write( "g = 15. A grammar book weighs 15 ounces, an algebra book, 2*15 - 6 = 24 ounces.
