\n" );

\n" );
document.write( "So, (10x-2x+11)/5 - (4x-6)/11 = (7-8x)/7 equals (10x-2x+11)/5 times 385(385 is the LCM of the denominators) - (4x-6)/11 times 385 = -(7-8x)/7 times 385, which equals 770x-154x+847-140x-210=-385-440x
\n" );
document.write( "Now, Transposition: 770x+440x-154x-140x=-385-847+210 which equals 916x=1442

I don't think I'm understanding how to work this kind of equation. I appreciate any help you can offer, if you can't understand or get the equation it's ok! \r
