bantu jawab,sama cara kerjanya yaa

2a+b=2
4b+3c=5
3a+2c=3

2a+b=2 → b=2-2a
4b+3c=5
→4(2-2a)+3c=5
→8-8a+3c=5
→-8a+3c=-3

3a+2c=3
-8a+3c=-3

9a+6c=9
-16a+6c=-6

25a=15
a=3/5

3a+2c=3
3(3/5)+2c=3
9/5+2c=9
2c=36/5
c=18/5

b=2-2a
b=2-2(3/5)
b=2-(6/5)
b=4/5

a=3/5 → 1/x
b=4/5 → 1/y
c=18/5 → 1/z

Silakan dicek lagi.
