You asked:

Evaluate the expression: \(2 - \frac{6 \cdot 4}{5} + \frac{6}{7} - 2 \cdot 10\)

MathBot Answer:

\[2 - \frac{6 \cdot 4}{5} + \frac{6}{7} - 2 \cdot 10 = - \frac{768}{35} = -21.9\overline{428571}\]

\[\begin{aligned}2 - \frac{6 \cdot 4}{5} + \frac{6}{7} - 2 \cdot 10& = 2 - 6 \cdot \frac{4}{5} + \frac{6}{7} - 2 \cdot 10\\& = 2 - \frac{24}{5} + \frac{6}{7} - 2 \cdot 10\\& = 2 - \frac{24}{5} + \frac{6}{7} - 20\\& = - \frac{14}{5} + \frac{6}{7} - 20\\& = - \frac{68}{35} - 20\\& = - \frac{768}{35}\end{aligned}\]
