\"x%2F2+-+y%2F3+=+-4\"
\n" ); document.write( "\"x%2F2+%2B+y%2F9+=+0\"
\n" ); document.write( ".
\n" ); document.write( "Ok i hate fractions so lets change the appearance so fractions arent a sore to look at.
\n" ); document.write( "Find a number thats divisible by 2, 3 and 9. The easiest is to multiply all 3 together but since 9is divisible by 3 all wee need is to multiply 2 and 9 to make 18.
\n" ); document.write( ".
\n" ); document.write( "Now multiply the top and bottom line by 18
\n" ); document.write( "The 2s will cancel out leaving 9x/1 and the 3 will cancel out to be 6y/1 and the 9 will cancel out to be 2y/1.
\n" ); document.write( ".
\n" ); document.write( "This shows as :
\n" ); document.write( "\"9x-6y=-72\"
\n" ); document.write( "\"9x%2B2y=0\"
\n" ); document.write( ".
\n" ); document.write( "Now much easier to see how to solve id go with subtraction so x cancels out and solve for y first.
\n" ); document.write( "\"-6y-2y=-72\" add like terms
\n" ); document.write( "\"-8y=-72\" divide by negative eight
\n" ); document.write( "\"highlight%28y=9%29\"
\n" ); document.write( "Plug in y and solve for x
\n" ); document.write( "\"9x%2B2y=0\"
\n" ); document.write( "\"9x%2B2%289%29=0\" multiply
\n" ); document.write( "\"9x%2B18=0\" subtract 18
\n" ); document.write( "\"9x=-18\" divide by 9
\n" ); document.write( "\"highlight%28x=-2%29\"
\n" ); document.write( "
\n" );
