## Homework Statement

Calculate v (refer to attachment).

## Homework Equations

Voltage division: Vout = Vin x R2 / R1 + R2

## The Attempt at a Solution

V1 = V1 x R2 / R1 + R2

= 15 x 5 / 10 + 5

= 5V

V2 = V2 x R4 / R3 + R4

= 5 x 2 / 10 + 2

= 0.83V

V = 5 + 0.83

= 5.83V

But my answer is wrong. Could someone please tell me whats wrong?
