#### Given:

VR Headset + 2 Controller + 2 Controller = 18

2 Controller – Camera Sensor = 2

#### Required:

Camera Sensor + VR Headset + 2 Controller = ?

### Solution:

#### Equation 1:

VR Headset = 30 / 3

#### Equation 2:

VR Headset + 2 Controller + 2 Controller = 18

Put value of VR Headset in above equation.

10 + 4 Controller = 18
4 Controller = 18 – 10
4 Controller = 8
Controller = 2

#### Equation 3:

2 Controller – Camera Sensor = 2

Put value of controller in above equation.

2 (2) – Camera Sensor = 2
4 – Camera Sensor = 2
Camera Sensor = 4 – 2
Camera Sensor = 2

Now we have values of all unknown variable & we can put these values in the final equation to find the value of unknown.

#### Equation 4:

Camera Sensor + VR Headset + 2 Controller = ?

2 + 10 + 4 = Unknown
