(2) x + 3y = 3
x = –y + 2
(3) x = 2y + 6
2x + 3y = 5
(4) 9x – 2y = –1
y = 3x + 1
(5) y = 2x – 1
y = –3x + 14
(6) 2x = 3y – 1
2x = 5y – 7
Jawaban:
3. Menggunakan Sistem Persamaan
(1) 8x = 5y + 2
5 – 3x = –4y
BERITA REKOMENDASI
(2) 3(2x + 1) + 5y = –5
–7x – 4(y + 3)= –10
(3) 0,5x – 1,4y = 8
–x + 2y = –12
(4) 0,35x – 0,12y = –1,5
–2x + 3y = –3
(5)
(6)
(7) 2x – y = 3x + y = –10
