3ts + 4t = 960.000
2ts + 5t = 990.000
_______________ x
6ts + 8t = 1.920.000
6ts + 15t = 2.970.000
_________________ -
-7t = -1.050.000
t = -1.050.000/-7
t = Rp. 150.000

3ts + 4t = 960.000
3ts + 4 x 150.000 = 960.000
3ts + 600.000 = 960.000
3ts = 960.000 - 600.000
3ts = 360.000
ts = 360.000/3
ts = Rp. 120.000,-

ts + t = 120.000 + 150.000
