20/15+х + 20/15-х=3

To solve this equation, we can simplify the left side by finding a common denominator for the fractions and combining like terms.

Given equation: \( \frac{20}{15} + x + \frac{20}{15} - x = 3 \)

Combine fractions with a common denominator of 15:

\( \frac{20+20}{15} + x - x = 3 \)

\( \frac{40}{15} = 3 \)

Now, simplify the fraction:

\( \frac{8}{3} = 3 \)

Since \( \frac{8}{3} \neq 3 \), the equation does not have a solution.
