-3.8q+1.8 [solve for the q-term]
\n" ); document.write( "-3.8q+1.8=0 [set the expression equal to zero]
\n" ); document.write( "-3.8q+1.8-1.8=0-1.8
\n" ); document.write( "-3.8q=-1.8
\n" ); document.write( "-3.8q/-3.8=-1.8/-3.8
\n" ); document.write( "q=.4737
\n" ); document.write( ".
\n" ); document.write( "check by plugging (q=.4737) back into the original equation:
\n" ); document.write( "-3.8(.4737)+1.8=0
\n" ); document.write( "-1.8+1.8=0
\n" ); document.write( "0=0 [checks out]
\n" ); document.write( " \n" ); document.write( "
