substituting the value of y from the first equation into the second __ -2x+3(2x+1)=-9\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "-2x+6x+3=-9 __ 4x=-12 __ x=-3\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y=2(-3)+1 __ y=-5
\n" ); document.write( "
\n" );
