Which of the following would be the best first step for solving the system of equations by elimination?
\n" ); document.write( "• 6.3x + 7.2y = 5.4
\n" ); document.write( "• 5.6x + 6.4y = 4.8\r
\n" ); document.write( "\n" ); document.write( "a) Multiply both equations by 10.
\n" ); document.write( "b) Multiply both equations by 100.
\n" ); document.write( "c) Divide the first equation by 9.
\n" ); document.write( "d) Divide the second equation by 8.
\n" ); document.write( "=================
\n" ); document.write( "I would multiply by 10 to eliminate fractions, as in a.
\n" ); document.write( "-------------
\n" ); document.write( "Doing both c & d is good, too.
\n" ); document.write( "\"best\" is not clearly defined math term.
\n" ); document.write( " \n" ); document.write( "
