Q.

carilah nilai x dan y hasilnya dijadikan pecahan campuran
4x + 2y = 13
3x + 1y = 9

3x + 1y = 9 |×2)

4x + 2y = 13
6x + 2y = 18
--------------------- (-)
2x = 5
lanjutin sendiri​

Materi : SPLDV

2x = 5 [ x = 5/2 ]

\___________/

3x + y = 9

3( 5/2 ) + y = 9

y = - 15/2 + 9

y = - 15/2 + 9/1

y = - 15/2 + 18/2

[ y = 3/2 ]

Hasil / Result :

( x = 5/2 atau y = 3/2 )

Semoga bisa membantu

Penjelasan dengan langkah-langkah:

4x + 2y = 13 (×1)

3x + 1y = 9 (×2)

• 4x + 2y = 13
• 6x + 2y = 18 –

------------------------

-2x = -5

x = 5/2 = 2½

4x + 2y = 13

4(5/2) + 2y = 13

10 + 2y = 13

2y = 13 - 10

2y = 3

y = 3/2 = 1½

HP = {x, y} = {2½, 1½}
