Ilustrasi belajar. - Simak kunci jawaban Matematika SMP kelas 8 halaman 43 Kurikulum Merdeka.
(8) 4x + 3y = 0
5x – 2y = –23
(9) 5x – 7y = –16
–4x – 3y = 30
Jawaban:
(1) x = 5
y = 2
(2) x = 3
y = –1
(3) x = 5
y = –1
(4) x = 1
y = 4
(5) x = –1
y = –2
(6) x = 0
y = –3
(7) x = –3
y = 1
(8) x = –3
y = 4
(9) x = –6
y = –2
2. Menggunakan Metode Substitusi
(1) y = x + 2
3x + y = 14
(2) x + 3y = 3
x = –y + 2
(3) x = 2y + 6
2x + 3y = 5
