How do you simplify #x/3 - x/7#?

Answer 1
The LCM of 3 and 7 is 21 so #(x xx 7)/(3 xx 7) - (x xx 3)/(7 xx 3)# #(7x)/21-(3x)/21# #(7x-3x)/21# #(4x)/21#

Answer 2

To simplify ( \frac{x}{3} - \frac{x}{7} ), you can find a common denominator and then combine the terms:

  1. Find the least common multiple (LCM) of 3 and 7, which is 21.
  2. Rewrite each fraction with the common denominator of 21: ( \frac{7x}{21} - \frac{3x}{21} )
  3. Combine the numerators: ( \frac{7x - 3x}{21} )
  4. Simplify the numerator: ( \frac{4x}{21} )

So, ( \frac{x}{3} - \frac{x}{7} ) simplifies to ( \frac{4x}{21} ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
