10p/p-q + 3p/p-q

To simplify the expression \( \frac{10p}{p-q} + \frac{3p}{p-q} \), we notice that both fractions have the same denominator, which is \( p - q \).

We can combine the fractions:

\[ \frac{10p}{p-q} + \frac{3p}{p-q} = \frac{10p + 3p}{p-q} \]

Now, we can combine the numerators:

\[ 10p + 3p = 13p \]

Now, substitute this back into the expression:

\[ \frac{13p}{p-q} \]

Thus, the simplified expression is:

\[ \frac{13p}{p-q} \]
