diket sistem persamaan linear 3×+4y=17 dan 4×-2y=8 nilai dri 2×+3y adlh?

Diketahui :
- 3x + 4y = 17
- 4x - 2y = 8

Ditanya : 2x + 3y = .....?

Penyelesaian :
- Nilai x :
(3x + 4y = 17) × 1
(4x - 2y = 8) × 2

3x + 4y = 17
8x - 4y = 16
_________+
11x = 33
x = 33/11
x = 3

- Nilai y :
4x - 2y = 8
4(3) - 2y = 8
12 - 2y = 8
- 2y = 8 - 12
- 2y = - 4
y = - 4/- 2
y = 2

- Nilai 2x + 3y :
2x + 3y
= 2(3) + 3(2)
= 6 + 6
= 12

Maaf Kalau Salah
