You are looking for a number ... so let's call the missing number X.
\n" ); document.write( ".
\n" ); document.write( "When \"twice a number (or 2X) is subtracted from 24\" is a statement that translates to:
\n" ); document.write( ".
\n" ); document.write( "24 - 2X
\n" ); document.write( ".
\n" ); document.write( "The problem says that the result equals 6 times the number (or 6X)
\n" ); document.write( ".
\n" ); document.write( "Set this up as an equation:
\n" ); document.write( ".
\n" ); document.write( "24 - 2X = 6X
\n" ); document.write( ".
\n" ); document.write( "Solve this equation by first getting all the terms containing X on one side of the equal sign
\n" ); document.write( "and all the plain numbers on the other side. You can do this by adding 2X to the left
\n" ); document.write( "side to cancel out the -2X. But if you add 2X to the left side, you must also add 2X to the
\n" ); document.write( "right side to keep the equation in balance. Adding 2X to both sides results in:
\n" ); document.write( ".
\n" ); document.write( "24 - 2X + 2X = 6X + 2X
\n" ); document.write( ".
\n" ); document.write( "combining the -2X and +2X on the left side results in them canceling out and this
\n" ); document.write( "makes the equation become just:
\n" ); document.write( ".
\n" ); document.write( "24 = 6X + 2X
\n" ); document.write( ".
\n" ); document.write( "Combining the 6X and +2X on the right side makes the equation:
\n" ); document.write( ".
\n" ); document.write( "24 = 8X
\n" ); document.write( ".
\n" ); document.write( "Solve by dividing both sides of this equation by 8 and you get:
\n" ); document.write( ".
\n" ); document.write( "24/8 = X
\n" ); document.write( ".
\n" ); document.write( "and after doing the division on the left side you get the answer of:
\n" ); document.write( ".
\n" ); document.write( "X = 3
\n" ); document.write( ".
\n" ); document.write( "as being the number you are trying to find.
\n" ); document.write( ".
\n" ); document.write( "Check ... from 24 subtract twice the number ... this is 24 - (2*3) = 24 - 6 = 18. Does
\n" ); document.write( "that equal 6 times the number or 6 times 3? 6 times 3 also equals 18. So the answer checks.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you to see how you just start breaking down a problem and converting
\n" ); document.write( "the given information into algebraic terms. Then solve the equation that results from
\n" ); document.write( "relating the algebraic terms to each other.
