Answer:

$\begin{equation*} 5(7a+5)-80=4(3a+15) \end{equation*}$

Explanation:

Given the equation:

First, find the lowest common multiple of the denominators 8 and 10.

• The LCM of 8 and 10 = 40

Then, multiply all through by 40:

$\begin{gathered} (40(7a+5))/(8)-2(40)=(40(3a+15))/(10) \\ \implies5(7a+5)-80=4(3a+15) \end{gathered}$

The third option is equivalent.
