metode eliminasi 2×+y=5 dan 3×-2y=4

2x+y=5 (dikali 2)
3x-2y=4(dikali 1)




⇒jadi 4x+2y=10           3x-2y=4 [ditambah]    jadi 7x=14             x=2
2x+y=54+y=5y=1

2x + y = 5 ... (1) [x2]
3x -2y = 4 ... (2) [×1]

4x + 2y = 10
3x -2y = 4
-----------------------+
7x = 14
x = 14/7
x = 2

2x + y = 5 ... (1) [x3]
3x -2y = 4 ... (2) [×2]

6x + 3y = 15
6x -4y = 8 -
-----------------------
7y = 7
y = 7/7
y = 1
jadi HP adalah (2,1)
