4×+3y=-5 -×+3y=-10 Please jawab dikumpulin besok

4x + 3y = - 5
- x + 3y = - 10

- x + 3y = - 10
- x = - 10 - 3y
x = 3y + 10

4x + 3y = - 5
4(3y + 10) + 3y = - 5
12y + 40 + 3y = - 5
15y = - 5 - 40
15y = - 45
y = - 3

x = 3y + 10
x = - 9 + 10
x = 1

Maaf Kalau Salah

4x +3y=-5 |-1| → -4x -3y= 5
-x+3y=-10 |4| → -4x +12y=-40
……………………………… -
- 15y = 45
y = -3

4x +3y = -5
4x + 3(-3)= -5
4x - 9 = -5
4x = -5+9
4x = 4
x = 1
maaf jika salah
