Question

Selesaikan dengan cara eliminasi
5x + 3y = 7

Answer 1

5x + 3y = 7 -> 5x= -3y+7 -> x= -3/5 + 7/5
jadi : 5x + 3y = 7 -> 5(-3/5 + 7/5) + 3y = 7
-> -3+7+3y = 7 -> 4+3y = 7
-> 3y = 7-4 -> 3y = 3
berarti y = 1
Sehingga : 5x + 3y = 7 -> 5x + 3.1 = 7 -> 5x + 3 = 7
5x = 7-3 -> 5x = 4
jadi x = 4/5

Maaf, kalau salah..
Semoga membantu :)
