You can put this solution on YOUR website!
$\"%281%2F9%29x-%281%2F5%29y=20%2F9\"$
\n" ); document.write( "The first thing we want to do here is get rid of those annoying denominators.
\n" ); document.write( "Multiplying each term in the equation by 9*5 or 45, would do this, leaving us with:
\n" ); document.write( "5x - 9y = 5(20)
\n" ); document.write( "5x - 9y = 100
\n" ); document.write( ":
\n" ); document.write( "On this equation I assume you mean:
\n" ); document.write( "-10x + 18y = -200
\n" ); document.write( ":
\n" ); document.write( "Now it becomes apparent that this system cannot be solved. See what happens if
\n" ); document.write( " we multiply the 1st equation by 2, and add to the 2nd equation:
\n" ); document.write( ":
\n" ); document.write( " 10x - 18y = 200
\n" ); document.write( "-10x + 18y = -200
\n" ); document.write( "------------------- adding eliminates everything!
\n" ); document.write( " 0x + 0y = 0
\n" ); document.write( ":
\n" ); document.write( "This is just a form of \"math student harassment\" don't you think? \n" ); document.write( "
