Algebra.Com's Answer #496011 by josgarithmetic(39617)![]() ![]() ![]() You can put this solution on YOUR website! It seems a linear algebra problem. Six students, six different questions, all asked of every student. Each question is of a different point value than other questions. The point value of each question is a variable, and you have six variables.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "A matrix might be like this: \n" ); document.write( "1, 1, 0, 1, 1, 0, 26 \n" ); document.write( "0, 1, 1, 0, 0, 1, 21 \n" ); document.write( "0, 0, 1, 1, 1, 1, 32 \n" ); document.write( "1, 1, 0, 1, 0, 1, 26 \n" ); document.write( "1, 0, 1, 0, 1, 0, 21\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Unfortunately, the last row in the reference does not give the total points as known so you only have FIVE equations; not six.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "I'd rather resort to software; regardless of any skill within linear algebra.
