Quiz!
[tex]x + 2y = 20 \\ 3x + 4y = 60[/tex]

Carilah nilai x dan y ​

Jawab:

Penjelasan dengan langkah-langkah:

x + 2y = 20

3x + 4y = 60

x = 20 - 2y

3(20 - 2y) + 4y = 60

60 - 6y + 4y = 60

-2y = 0

y = 0/(-2) = 0

x = 20 - 2(0)

x = 20 - 0

x = 20

HP = {x, y} = {20, 0}

Jawab:

(20,0)

Penjelasan dengan langkah-langkah:

[tex]\begin{aligned} x+2y=20\\3x+4y = 60 \end{aligned}\\\\3x+4y = 3(x+2y)\\\\4y = 6y \to \boxed{\boxed{y = 0, x=20}}[/tex]
