Titik potong antara garis y=4x-11 dengangaris 3y=-2x-5adalah

y = 4x - 11
y - 4x = -11

3y = -2x - 5
3y + 2x = -5

y - 4x = -11 >> × 1
3y + 2x = -5 >> × 2
_________________
y - 4x = -11
6y + 4x = -10
___________+
7y = -21
y = -3

y - 4x = -11
-3 - 4x = -11
-4x = -11 + 3
-4x = -8
x = -8 : (-2)
x = 2

titik potong = (2, -3)

y = 4x - 11
y - 4x = -11
3y = -2x - 5
3y + 2x = -5
y - 4x = -11 >> × 1
3y + 2x = -5 >>

Jadi titik potongnya = 2, -3
Kayanya sih gitu :v
