jasil dari 2y-x=4 dan y=4x-5 menggunakan metode subtitusi

2y - x = 4
y = 4x - 5

2y - x = 4
2(4x - 5) - x = 4
8x - 10 - x = 4
7x = 4 + 10
7x = 14
x = 14/7
x = 2

y = 4x - 5
y = 8 - 5
y = 3

Maaf Kalau Salah

2y-x = 4 |x1 | 2y-x = 4
y-4x =-5 |x2| 2y-8x = -10
----------------- --
7x = 14
x = 2
2y - x = 4
2y - 2 = 4
2y= 4+2
2y= 6
y = 3
