To solve the equation \(5A - 8B = 170\) for \(A\), you want to isolate \(A\) on one side of the equation. Here are the steps:

  1. Start with the original equation: \[ 5A - 8B = 170 \]

  2. Add \(8B\) to both sides to move the term involving \(B\) to the other side: \[ 5A = 170 + 8B \]

  3. Next, divide both sides by 5 to solve for \(A\): \[ A = \frac{170 + 8B}{5} \]

Now, the expression for \(A\) is: \[ A = \frac{170 + 8B}{5} \]

This is your simplified answer for \(A\).
