Answer

The expression simplifies to \( \frac{p + 7}{5m} \).

Solution

Since the two fractions have the same denominator, 5m, you can combine them by adding their numerators:   (4p)/(5m) + (7 - 3p)/(5m) = (4p + 7 - 3p)/(5m). Now, combine the like terms in the numerator:   4p - 3p = p. So the expression simplifies to:   (p + 7)/(5m).

Bonus Knowledge

Let's combine the fractions! Since they have the same denominator, we can add the numerators directly: \[ \frac{4p + (7 - 3p)}{5m} \] This simplifies to: \[ \frac{4p + 7 - 3p}{5m} = \frac{(4p - 3p) + 7}{5m} = \frac{p + 7}{5m} \] So, the final result is: \[ \frac{p + 7}{5m} \]
