Where did I go wrong?

Solution

Let's go through each step of your work to identify where the mistake might be.

  1. Original Equation: 160x+140(50x)=1\frac{1}{60}x + \frac{1}{40}(50 - x) = 1

  2. Finding a Common Denominator: To solve this equation, it’s best to clear the fractions by finding a common multiple for 60 and 40, which is 120. Multiply each term by 120: 120160x+120140(50x)=1201120 \cdot \frac{1}{60}x + 120 \cdot \frac{1}{40}(50 - x) = 120 \cdot 1 Simplifying each term: 2x+3(50x)=1202x + 3(50 - x) = 120

  3. Expanding and Simplifying: Expanding 3(50x)3(50 - x): 2x+1503x=1202x + 150 - 3x = 120 Combine like terms: x+150=120-x + 150 = 120 Isolate xx by moving constants: x=30-x = -30 Thus, x=30x = 30.


Explanation of the Mistake

In your steps, it looks like you complicated the approach with multiple conversions and over-expanded terms, which led to unnecessary complexity. This may have caused the incorrect values in the final calculations.
