1. Given
Call the number of guests at the wedding x
of the guests ordered beef,
x ordered beef
of the guests ordered chicken,
x ordered chicken
69 guests ordered vegetarian.
2. Solving

x +
x + 69 = x
Simplify,
- convert fractions to a common denomintor
- reduce fractions
x +
x + 69 = x
x + 69 = x
x + 69 = x
69 = x - x
69 = x
*4 *4
276 = x
