Materi : SPLDV

Pemisalan :

( x ) = kambing

( y ) = ayam

____________/

x + y = 60 [ kepala ] ( x = 60 - y )

4x + 2y = 170 [ kaki ]

4( 60 - y ) + 2y = 170

240 - 4y + 2y = 170

4y - 2y = 240 - 170

2y = 70

[ y = 35 ekor ]

x = 60 - y

x = 60 - 35

[ x = 25 ekor ]

Answer 2

Jawaban:

x = ayam

y = kambing

a) x + y = 60,

x = 60 - y

b) 2x + 4y = 170, bisa disederhanakn

x + 2y = 85

60-y + 2y = 85

y = 85 - 60

y = 25, jadi jumlah kambing 25 ekor

x + y = 60

x + 25 = 60

x = 60 - 25

x = 35, jadi jumlah ayam 35 ekor
