2x-y-5=0 dan x+2y-1=0

2x - y - 5 = 0
2x - y = 5 ... Persamaan (1)
x + 2y -1 = 0
x + 2y = 1 ... Persamaan (2)

Eleminasi Pers (1) dan (2)
2x - y = 5 dikali 2
x + 2y = 1 dikali 1

4x -2y = 10
x + 2y = 1
................... +
5x = 11
x = 11/5

Substitusikan ke pers (2)
x + 2y = 1
11/5 + 2y = 1
2y = 1 - 11/5
2y = 5/5 - 11/5
2y = -6/5
y = -6/5 : 2
y = -6/5 × 1/2
y= -6/10
y = -3/5

Hp {11/5, -3/5}
