solve by addition. Indicate whether each system is independent, dependent or inconsistent.
\n" ); document.write( "-3x + 1y = 3
\n" ); document.write( "2x - 3y = 5\r
\n" ); document.write( "\n" ); document.write( "------
\n" ); document.write( "Multiply thru the 1st equation by 3:
\n" ); document.write( "-9x + 3y = 9
\n" ); document.write( "2x - 3y = 5
\n" ); document.write( "------
\n" ); document.write( "Add and solve for \"x\":
\n" ); document.write( "-7x = 14
\n" ); document.write( "x = -2
\n" ); document.write( "------
\n" ); document.write( "Solve for \"y\":
\n" ); document.write( "2x-3y = 5
\n" ); document.write( "2(-2)-3y = 5
\n" ); document.write( "-4 - 3y = 5
\n" ); document.write( "-3y = 9
\n" ); document.write( "y = -3
\n" ); document.write( "----------
\n" ); document.write( "The system has a single solution.
\n" ); document.write( "The system is independent.
