Verified answer
3x + 2y - 4 = 03x + 2y = 4 ... pers 1
x - 3y - 5 = 0
x - 3y = 5 ... pers 2
3x + 2y = 4
x - 3y = 5 |×3
3x + 2y = 4
3x - 9y = 15
------------------(-)
11y = - 11
y = - 1
x - 3y = 5
x - 3(-1) = 5
x + 3 = 5
x = 5 - 3
x = 2
hp = {2,-1} (B)
3x + 2y = 4
3x - 9y = 15
Kurangkan
11y = -11
y = -1 ✔
x = 5 + 3y
x = 5 + (-3)
x = 2 ✔
