4/7 is the result when 1/2 and x are added
- 4/7 is the result: = 4/7
- when 1/2 and x are added: 1/2 + x
1/2 + x = 4/7
- Subtract 1/2 from both sides.
x = 4/7 - 1/2
- Make 4/7 and 1/2 have common denominators by multiplying 4/7 by 2/2 and 1/2 by 7/7.
- 4/7 * 2/2 = 8/14
- 1/2 * 7/7 = 7/14
- Rewrite the equation using the fractions with common deniminators.
x = 8/14 - 7/14 = 1/14
x = 1/14
