tolong dijawab... himpunan penyelesaian dari SPLDV berikut degan metode gabungan... A. 3x+2y=6 dan 2x-y=5 tolong.. yang jawab benar saya jadikan jawaban ter b

A.
3x + 2y = 6 ( × 2)
2x - y = 5 ( × 3)

》 6x + 4y = 12
》6x - 3y = 15
》_____________ _
》7y = 27
》y = 27/7
》y = 3 6/7

2x - y = 5
2x - 27/7 = 5
2x = 5 + 27/7
2x = 35/7 + 27/7
2x = 62/7
x = 62/7/2
x = 62/7 × 1/2
x = 62/14
x = 4 6/14
x = 4 3/7
