1. Jawaban allin5
*30x + 24y = 195.000(1)
= 30x+24y=195000
*11x + 8y = 67.500(3)
=33x+24y = 202.500
*30x+24y=195000
33x+24y=202500
______________ _
-3x = - 7500
x = -7500/-3 = 2500
11x + 8y=67 500
11(2500)+8y=67.500
27500+8y=67.500
8y=67.500-27.500
8y=40.000
y= 40.000/8
y=5000
y+x=5000+2500
y+x=7500
