Berapa hasil dari x+3y=9 2x+y=4 . tolong pake cara Yach… thanks​

X + 3y = 9 ——-> x = 9 – 3y
2x + y = 4 ——-> y = 4 – 2x
2 ( 9 – 3y) + y = 4
18 – 6y + y = 4
-6y + y = 4 – 18
-5y = -14
y = 14/5

x + 3y = 9
x + 3( 4 – 2x ) = 9
x + 12 – 6x = 9
x – 6x = 9 – 12
-5x = -3
x = 3/5

Hp = { ( 3/5 , 14/5)}

Semoga bisa membantu
