You asked:
Given \(\frac{4}{5} = \frac{2 x}{7}\) evaluate the expression \(2 x\).
MathBot Answer:
\[2 x = \frac{28}{5}\]
\[\begin{aligned}\frac{4}{5} &= \frac{2 x}{7}\\- \frac{2 x}{7} &= - \frac{4}{5}\\x &= \frac{14}{5}\end{aligned}\]
By substituting this value into the expression, we find that: $$\begin{aligned}2 x &= 2 \cdot \frac{14}{5}\\&= \frac{28}{5}\end{aligned}$$
