x+3y=23 or x=23-3y
\n" ); document.write( "3x-2y=3
\n" ); document.write( "3(23-3y)-2y=3
\n" ); document.write( "69-9y-2y=3
\n" ); document.write( "-11y=3-69
\n" ); document.write( "-11y=-66
\n" ); document.write( "y=-66/-11
\n" ); document.write( "y=6 answer.
\n" ); document.write( "x=23-3*6
\n" ); document.write( "x=23-18
\n" ); document.write( "x=5 answer.
\n" ); document.write( "Proof:
