Explanation:

Step1: Count bags and bills

Left side: $4x + 3$, Right side: $13$
Equation: $4x + 3 = 13$

Step2: Subtract 3 from both sides

$4x + 3 - 3 = 13 - 3$
$4x = 10$

Step3: Divide by 4 on both sides

$x = \frac{10}{4} = 2.5$

Answer:

The equation is $4x + 3 = 13$, and the value of a single bag of chips is $x = 2.5$ dollars.
