Question

2x-y=4 dan -2x-3y=-4
hasil ya brapa dan caranya ya

Answer 1

Persamaan pertama dikali 3
6x-3y=12
-2x-3y=-4
dieliminasi, 8x=16
x=2
y=0

Answer 2

2x -y = 4 --------> y = 2x -4
-2x -3y = -4

-2x -3y = -4
-2x -3(2x -4) = -4
-2x -6x +12 = -4
-8x = -4 -12
-8x = -16
x = -16/-8
x = 2

y = 2x -4
y = 2(2) -4
   = 4 -4
   = 0

Jadi, HP = {2,0}.
