To simplify the expression, we need to combine like terms and simplify the fractions.

First, let's simplify the fractions separately:

11 - 2x / 3x + 1 = (11 - 2x) / (3x + 1)

5x - 10 / 3x + 1 = (5x - 10) / (3x + 1)

Now, let's combine the fractions:

(11 - 2x) / (3x + 1) + (5x - 10) / (3x + 1)

Since the denominators are the same, we can combine the numerators:

(11 - 2x + 5x - 10) / (3x + 1)

Combine like terms in the numerator:

(3x + 1) / (3x + 1)

The numerator and denominator are the same, so the simplified expression is:
