1. **State the problem:** Simplify the expression $$x \approx y + z + x + y + u + o$$. 2. **Combine like terms:** Group the terms with the same variables together. $$x + x + y + y + z + u + o$$ 3. **Simplify the grouped terms:** $$2x + 2y + z + u + o$$ 4. **Final simplified expression:** $$x \approx 2x + 2y + z + u + o$$ This means the right side is approximately equal to the left side, with the combined terms shown.
