himpunan penyelesaian dati 3x+2y=17 dan 5x-2y=7 adalah

Bab SPLDV
Matematika SMP Kelas VIII

3x + 2y = 17
5x - 2y = 7
------------------- +
8x = 24
x = 3

3x + 2y = 17
3 . 3 + 2y = 17
2y = 17 - 9
y = 8/2
y = 4

HP = { (3, 4) }

3x + 2y =>> 17
5x - 2y =>> 7
_____________ +
8x =>> 24
x =>> 24/8
x =>> 3

3x + 2y =>> 17
9 + 2y =>> 17
2y =>> 17+9
2y =>> 26
y =>> 26/2
y =>> 13
