3x + 2y = 17 | x2 => 6x + 4y = 34
2x + 3y = 8 | x3 => 6x + 9y = 24
----------------------- (-)
- 5y = 10
- y = 2
y = - 2
2x + 3y = 8
2x + 3(-2) = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 7
(x,y) = (7 , - 2) -
2. Jawaban Egi01
2x + 3y = 8
2x + 3(-2) = 8
2x - 6 = 8
2x = 8 + 6
2x = 14
x = 7
(x,y) = (7 , - 2)
