Write the coefficient matrix of the system of equations below.
\n" ); document.write( "{5x-9y+5z=-8
\n" ); document.write( "{-6x-y-9z=-2
\n" ); document.write( "{2x+9y-7z=-2
\n" ); document.write( "----
\n" ); document.write( "Just put the coefficients into a 3x3 matrix:
\n" ); document.write( "5...-9...5
\n" ); document.write( "-6..-1..-9
\n" ); document.write( "2....9..-7
\n" ); document.write( "====================
