You can put this solution on YOUR website!
your equation becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "20% of 600 = 15% of 60x - x
\n" ); document.write( "this is equivalent to:
\n" ); document.write( ".2*600 = .15*60x - x
\n" ); document.write( "simplify this to get:
\n" ); document.write( "120 = 9x - x
\n" ); document.write( "factor out the x on the right side of the equation to get:
\n" ); document.write( "120 = (9-1)*x
\n" ); document.write( "simplify to get:
\n" ); document.write( "120 = 8x
\n" ); document.write( "divide both sides of the equation by 8 to get:
\n" ); document.write( "120/8 = x
\n" ); document.write( "simplify to get:
\n" ); document.write( "15 = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your solution is x = 15
\n" ); document.write( "plug that back into the original problem statement to see if the equation is true.
\n" ); document.write( "your original problem statement is:
\n" ); document.write( "20% of 600 is x less than 15% of 60x.
\n" ); document.write( "replace x with 15 and your problem statement becomes:
\n" ); document.write( "20% of 600 is 15 less than 15% of 60*15
\n" ); document.write( "simplify this to get:
\n" ); document.write( "120 is 15 less than 15% of 900
\n" ); document.write( "simplify this further to get:
\n" ); document.write( "120 is 15 less than 135 which makes 120 equal to 120 which is correct.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "your solution is confirmed as good.
\n" ); document.write( "x = 15\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
