You can put this solution on YOUR website!
One of the things that you can do with equations in algebra, is check your answer
\n" ); document.write( "in the original problem, for instance if you get x = 4, replace x in the original
\n" ); document.write( "problem with 4 and see if equality is preserved, (right side value = left side value.) Do this for every equation problem that you have, both homework and in the final. You will find math mistakes and other errors this way.
\n" ); document.write( ":
\n" ); document.write( "If the problem is not an equation, an expression that you must simplify, then
\n" ); document.write( "assign a value (like 2) to the variables in the original expression, find the value. Do the same with your simplified expression, they should be equal
\n" ); document.write( ":
\n" ); document.write( "Sometimes assigning a value of 2 will cause you to have a 0 in the denominator;
\n" ); document.write( "This of course is not allowed. Then assign another value like 3 and do the same
\n" ); document.write( "thing \n" ); document.write( "

\n" );
