No 1. 5p + q = 10 14 + 3q = 18 No 2. y = x 2x + y = 5 Soal Persamaan linear 2 variabel Please banget Jawab cepat

5p+q=10 (x3) 15p+3q=30
3q=4 (x1) 3q=4 atas dikurang
bawah. 15p=26
p=26/15
15*26/15+3q=30
3q=30-26
q=4/3

1.
14 + 3q = 18
3q = 18 - 14
3q = 4
q = 4/3
q = 1 1/3

5p + q = 10
5p + 4/3 = 10
5p = 10 - 4/3
5p = 30/3 - 4/3
5p = 26/3
p = 26/3 × 1/5
p = 26/15
p = 1 11/15
Jadi HPnya adalah {(1 11/15 , 1 1/3)}
2.
y = x
2x + y = 5
2x + x = 5
3x = 5
x = 5/3
x = 1 2/3

y = x = 1 2/3

Jadi HPnya adalah {(1 2/3 , 1 2/3)}
