S = sendok
g = garpu
4s + 5g = 54.900 | x1 | 4s + 5g = 54.900
2s + 3g = 30.700 | x2 | 4s + 6g = 61.400 -
-g = -6500
9 = -6500/-1 = 6500
2s + 3g = 30.700
2s + 3(6500) = 30700
2s + 19500 = 30700
s = (30700 – 19500) : 2 = 5600
Jadi,,
s + g = 5600 + 6500
= 12.100
maaf kalo salah…

4x+5y=54,900(x1) –> 4x+5y=54,900
2x+3y=30,700(x2) –> 4x+6y=61,400
-y=-6500 –> y=6500
2x+3(6500)=30,700 2x=30,700-19,500 x=5600
2x+19,500=30,700 2x=11,200
x+y=5600+6500=Rp.12,100,00
