You can put this solution on YOUR website!
In this problem:\r
\n" ); document.write( "\n" ); document.write( "\"%28x%2B1%29%2F%282x-4%29\"=\"4%2F5\"\r
\n" ); document.write( "\n" ); document.write( "you would cross multiply the fractions.\r
\n" ); document.write( "\n" ); document.write( "\"%285%29%28x%2B1%29=%284%29%282x-4%29\"\r
\n" ); document.write( "\n" ); document.write( "Next is to multiply.\r
\n" ); document.write( "\n" ); document.write( "\"5x%2B5=8x-16\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now you want to solve for x by getting it by itself.
\n" ); document.write( "You can subtract the 8x from the right side (either 8x or 5x will work)\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"5x-8x%2B5=-16\"\r
\n" ); document.write( "\n" ); document.write( "Now combine like terms.\r
\n" ); document.write( "\n" ); document.write( "\"-3x%2B5=-16\"\r
\n" ); document.write( "\n" ); document.write( "Now, subtract the 5 to the other side of the equation.\r
\n" ); document.write( "\n" ); document.write( "\"-3x=-21\"\r
\n" ); document.write( "\n" ); document.write( "Next, divide -3 into itself and the other side of the equation.\r
\n" ); document.write( "\n" ); document.write( "\"-3x%2F-3=-21%2F-3\"\r
\n" ); document.write( "\n" ); document.write( "Now your answer:\r
\n" ); document.write( "\n" ); document.write( "x=7\r
\n" ); document.write( "\n" ); document.write( "Remember: positive X negative = negative
\n" ); document.write( " negative X negative = positive
\n" ); document.write( "
\n" );
