Selesaikan dengan metode subtitusi
1. 4x - 2y = 16
2x - 3y = 12
1. 4x - 2y = 16
2x - 3y = 12
2 Jawaban
-
1. Jawaban zerozonk
4x-2y = 16 | x1
2x-3y= 12 | x2
_____________
4x-2y=16
4x-6y=24
_____________ _
4y = -8
y = -2 -
2. Jawaban endah158
4x - 2y = 16 || X 1
2x - 3y = 12 || X 2
------------------
4x - 2y = 16
4x - 6y = 24
----------------- -
4y = - 8
y = -8/4
y = -2
lalu masukkan ke salah satu 4x - 2y = 16
4x - 2(-2) = 16
4x + 4 = 16
4x = 16 - 4
4x = 12
x = 3
jadi X,Y = ( 3, -2 )
