4.

The equation we have is:


(8)/(5)a=-6

To solve for "a", we want to isolate it in one side.

For this. we can start by multiplying each side by 5. This will make the denominator to cancel out:


\begin{gathered} 5\cdot(8)/(5)a=5\cdot(-6) \\ 8a=-30 \end{gathered}

Now, we can divide both sides by 8, which will cancel the coefficient 8 multiplying "a":


\begin{gathered} (8a)/(8)=-(30)/(8) \\ a=-(15)/(4) \end{gathered}

And that is the answer to 4.
