Question

A+B+C=23
A=C+4
B+C=13
Bagaimanakah menyelesaikan SPLTV di atas?

Answer 1

Verified answer

A = C + 4

B + C = 13
B = 13 - C

(C + 4) + (13 - C) + C = 23
C + 13 - C + C = 23 -4
C - C + C = 19 - 13
C = 6

A = C + 4
A = 10

B = 13 - C
B = 13 - 6
B = 7

Pembuktian :
A + B + C = 23
10 + 7 + 6 = 23
23 = 23
(benar)

Answer 2

A+B+C=23. A=C+4. B+C=13. Diperoleh, A+13=23. A=23-13. A= 10. Diperoleh, 10+B+(10-4)=23. 16+B=23. B=23-16. B=7. Diperoleh, 10+7+C=23. 17+C=23. C=23-17. C=6. Jadi nilai A=10, B=7, dan C=6
