Diego spent $3100 on a laptop, a VR headset, and a gaming mouse. The laptop cost $1900 more than the mouse and VR headset combined. The VR headset cost three times as much as the mouse. How much did the VR headset cost?

Let's say the laptop costs 6x. the VR headset costs $y. The laptop cost $2.    So { x + y + z = 3100 1

                      { x - (y+z) = 1900 2

                      {    y = 32             3
3->2     x - 42 = 1900  4

3->1     x + 42 = 3100 5

 4+5      2x = 5000           x = 2500

x - 42 = 1900             z=150

y = 32                      y = 450

 

 

 

450 is the answer
