3x1 + 3x2 + 2x3 = 810
x1 + 2x2 + x3 = 410
2x1 + x2 +2x3 = 490
3x1 + 3x2 + 2x3 = 810
- 2x1 - 4x2 - 2x3 = - 820
-----------------------------------
x1 - x2 = - 10
x1 + 2x2 + x3 = 410, by - 2
2x1 + x2 +2x3 = 490
-------------------------------
- 2x1 - 4x2 - 2x3 = - 820
2x1 + x2 + 2x3 = 490
------------------------------------
- 3x2 = - 330
x2 = 110
x1 - x2 = - 10
x1 = 100
x1 + 2x2 + x3 = 410
x3 = 410 - 100 - 220
x3 = 90
x1 = transistor 100
x2 = resistor 110
x3 = chip 90
