3x + 2y = 245x - 4y = 40
5x - 4y = 40
- 4y = 40 - 5x
4y = 5x - 40
y = 5/4x - 10
3x + 2y = 24
3x + 2(5/4x - 10) = 24
3x + 10/4x - 20 = 24
4(3x + 10/4x - 20 = 24)
12x + 10x - 80 = 96
22x = 96 + 80
22x = 176
x = 8
y = 5/4x - 10
y = 10 - 10
y = 0
Maaf Kalau Salah

Materi : SPLDV3x + 2y = 24 kalikan setiap ruas dengan 2
6x + 4y = 48
4y = 48 - 6x
subtitusikan 4y = 48 - 6x ke
5x - 4y = 40
5x - (48 - 6x) = 40
5x - 48 + 6x = 40
11x = 88
x = 8
subtitusikan x = 8 ke
4y = 48 - 6x
4y = 48 - 6(8)
4y = 48 - 48
y = 0
jadi HP : {(8,0)}
