3s + 2k = 292.500 |x1
4s + 2k = 360.000
3s + 2k = 292.500
--------------------------- -
s = 67.500
3.67.500 + 2k = 292.500
202.500 + 2k = 292.500
2k = 292.500 - 202.500
2k = 90.000
k = 90.000 : 2
k= 45.000
s+ k =
67.500 + 45.000 = 112.500
semoga membantu

2x + 1y = 180.000 |*3| 6x + 3y = 540.000
3x + 2y = 292.500 |*2| 6x + 4y = 585.000 _
-y = -45.000
y = 45.000
2x + 1(45.000) = 180.000
2x + 45.000 = 180.000
2x = 180.000 - 45.000
2x = 135.000
x = 135.000/2
x = 67.500
67.500 + 45.000 = 112.500
