maaf kalo salah
b = tas
Jwab =
2a + 3b =350.000 | ×1 | 2a + 3b = 350k
3a + b = 300.000. | ×3 | 9a + 3b = 900k
2a + 3b = 350.000
9a + 3b = 900.000
______________-
-7a = - 550000
a = -550.000 / -7
a = 78.571 = 78.600
2a + 3b = 350000
2(78.571 ) + 3b = 350.000
157.143 + 3b = 350.000
3b = 350.000 - 157.143
3b = 192.857
b = 192.857 : 3
b = 64.286 = 64.300
a + b =...
78.600+ 64.600 = 142.900
