Adakah anda masih ingat bentuk persamaan linear
Ingat
Entahlah, tak ingat....
3
Contoh persamaan linear:
y=2x+3
y=-10x +2
3y+2x=5
Sekarang dah ingat???
4
Untuk menyelesaikan persamaan serentak yang mengandungi 2 pembolehubah, semestinya ada 2 persamaan
mari kita selesaikan 2 persamaan yang terdiri dari satu persamaan linear dan satu persamaan bukan linear
5
Jika anda memperolehi persamaan kuadratik, selesaikan menggunakan kalkulator
slide sebelum ini, kita dapat m2+5m-3=0, tekan mode mode eqn

Multiple Choice
5y +x = 1
x = 1 −5y
x =−1 −3y2
y = 51−x
y = 3−1−x

Multiple Choice
x dan y ialah dua integer. Beza antara dua integer ini ialah 3, manakala hasil tambah bagi kuasa dua integer-integer itu ialah 89. Cari nilai-nilai yang mungkin bagi x dan y.
x = -8, y = -5
x = 5, y = 8
x = -5 , y = -8
x = 8, y = 5
15
Multiple Choice
Selesaikan persamaan serentak
x – 3y + 4 = 0
x2+xy – 40 = 0
x = 5, y = 13 ; x = – 7 , y = – 2/3
x = 5, y = 4 ; x = – 7 , y = – 2/3
x = 10, y = 3 ; x = – 6 , y = – 4/3
x = 5, y = 3 ; x = – 6 , y = – 2/3

Multiple Choice
Selesaikan persamaan serentak
p – m = 2 dan p2+2m = 8.
m = 0.606, p=2.606 ; m = –6.606 , p = 4.606
m = 1.606, p=2.606 ; m = –7.606 , p = – 4.606
m = 0.606, p=-2.606 ; m = 6.606 , p = 4.606
m = 0.606, p=2.606 ; m = –6.606 , p = – 4.606

Multiple Choice
Selesaikan persamaan serentak
4x + y = – 8 dan x2 + x – y = 2.
x = 2 , y = 0 ; x = –3 , y = 4
x = –2 , y = 0 ; x = 3 , y = 4
x = –2 , y = 0 ; x = –3 , y = 4
x = 0 , y = 2 ; x = –3 , y = -4

Multiple Choice
Selesaikan persamaan serentak yang berikut dengan menggunakan kaedah penggantian.
2x−y=6
x2−y2+x=4y
x = -0.83, y = 4.35
x = -4.84, y = -3.68
x = 0.83, y = -4.35
x = 4.84, y = 3.68
x = -2.46, y = -10.92
x = 8.13, y = 10.26
x = 2.46, y = 10.92
x = -8.13, y = -10.26
