Jika:

2♣ + ♥ = 16
3♣ + 2♥ = 27

Nilai ♥ – ♣ = …

Nilai ♥ – ♣ adalah 1

Pembahasan

Diketahui :

2♣ + ♥ = 16 pers(1)

3♣ + 2♥ = 27 pers(2)

Ditanya :

♥ – ♣?

Dijawab :

Eliminasi pers(1) dan (2)

2♣ + ♥ = 16 |×3| 6♣ + 3♥ = 48

3♣ + 2♥ = 27 |×2| 6♣ + 4♥ = 54

————————— –

-1♥ = -6

♥ = -6/-1

♥ = 6

Substitusi nilai ♥ = 6 ke pers(1)

2♣ + ♥ = 16

2♣ + 6 = 16

2♣ = 16 – 6

2♣ = 10

♣ = 10/2

♣ = 5

Cari nilai ♥ – ♣

= ♥ – ♣

= 6 – 5

= 1

Kesimpulan

Jadi, nilai ♥ – ♣ adalah 1
