Kerjakan soal dibawah ini dengan cara eliminasi 2x + 2y =2 2x - 2y =12

2x + 2y = 2
2x - 2y = 12
_________ _
4y = -10
y = -10/4
y = -5/2
y = -2 ¹/₂

2x + 2y = 2
2x - 2y = 12
_________ +
4x = 14
x = 14/4
x = 7/2
x = 3 ¹/₂

Semoga membantu :)

2x + 2y = 2
2x -2y = 12
_________ +
4x = 14
x = 3,5

2x + 2y = 2
2(3,5) + 2y = 2
7 + 2y = 2
2y = 2-7
2y = -5
y = -5/2
atau y = -2,5
