Algebra.Com's Answer #332650 by bucky(2189) ![]() You can put this solution on YOUR website! You can get rid of the \"a\"s in the denominator by multiplying all terms on both sides by a as follows: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "The a in the numerator cancels with the a in the denominator as follows: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "and what's left is: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Subtract 4a from both sides: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "and this simplifies to: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Next subtract 1 from both sides: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "On the left side the +1 and -1 cancel each other out and this reduces the equation to: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Solve for a by dividing both sides by -2: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "and the answer becomes: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "That's the answer to this problem. \n" ); document.write( ". \n" ); document.write( "Hope this helps you to see your way through the problem. \n" ); document.write( " \n" ); document.write( " |
