Tentukan penyelesaian SPLDV 2x + 3y=-4 dan 3x-2y=-19 dengan metode substitusi!

2x + 3y = - 4
3x - 2y = - 19

3x - 2y = - 19
- 2y = - 19 - 3x
2y = 3x + 19
y = 3/2x + 19/2

2x + 3y = - 4
2x + 3(3/2x + 19/2) = - 4
2x + 9/2x + 57/2 = - 4
2(2x + 9/2x + 57/2 = - 4)
4x + 9x + 57 = - 8
13x = - 8 - 57
13x = - 65
x = - 5

y = 3/2x + 19/2
y = 3/2 × (- 5) + 19/2
y = - 15/2 + 19/2
y = 4/2
y = 2

Maaf Kalau Salah

y=4/2
y=2

maaf kalo salah
