4/7 is the result when 1/2 and x are added

  1. 4/7 is the result: = 4/7
  2. when 1/2 and x are added: 1/2 + x

1/2 + x = 4/7

  1. Subtract 1/2 from both sides.

x = 4/7 - 1/2

  1. Make 4/7 and 1/2 have common denominators by multiplying 4/7 by 2/2 and 1/2 by 7/7.
  2. 4/7 * 2/2 = 8/14
  3. 1/2 * 7/7 = 7/14
  4. Rewrite the equation using the fractions with common deniminators.

x = 8/14 - 7/14 = 1/14

x = 1/14
