Question - Solving a Mathematical Expression

First, simplify the expression inside the parentheses:

\(+\frac{7}{3} = \frac{7}{3}\)

Now substitute this back into the expression:

24 \left( \frac{7}{3} \right) - (-1)

which simplifies to:

24 \cdot \frac{7}{3} + 1 = 24 \cdot \frac{7}{3} + \frac{3}{3}

= \frac{168}{3} + \frac{3}{3} = \frac{171}{3}

= 57.
