Materi : SPLTV

[ A + B = 10 ] <= pakai substitusi ini

A + C = 12

B + C = 12

\__________/

A + B + C = 17

( A + B ) + C = 17

10 + C = 17

C = 17 - 10

[ C = 7 ]

()()()()()()()

A + C = 12

A + 7 = 12

A = 12 - 7

[ A = 5 ]

()()()()()()()

B + C = 12

B + 7 = 12

B = 12 - 7

[ B = 5 ]

Hasil / Result :

( A = 5, B = 5, C = 7 )

Semoga bisa membantu

Jawab:

Penjelasan dengan langkah-langkah:

Diketahui

A + B = 10

A + C = 12

B + C = 12

A + B + C = 17

Maka

A = ...

B = ...

C = ...

=============================================

A + B  = 10

A = - B + 10

A + C = 12

- B + 10 + C = 12

- B + C = 12

C = B + 12

B + C = 12

B + ( B + 12 ) = 12

2B + 12 = 22

2B = 10

B = 5

A + B = 10

A + 5 = 10

A = 5

A + B + C = 17

10 + C = 17

C = 7
