solve using the addition method.
\n" ); document.write( "2x - 3y = -6
\n" ); document.write( "x + y = 7
\n" ); document.write( "------------
\n" ); document.write( "multiply thru the 2nd eqution by 2 to get
\n" ); document.write( "2x+2y = 14
\n" ); document.write( "-------
\n" ); document.write( "Subtract this from the 1st equation to get:
\n" ); document.write( "-5y = -20
\n" ); document.write( "y = 4
\n" ); document.write( "-------------------
\n" ); document.write( "Substitute that into x+y = 7
\n" ); document.write( "x + 4 = 7
\n" ); document.write( "x = 3
\n" ); document.write( "------------
\n" ); document.write( "Solution :(3,4)
