titik potong antara garis y = 4x - 11 dengan garis 3y = -2x -5

3y = -2x - 5
3(4x - 11) = -2x - 5
12x - 33 = -2x - 5
12x + 2x = 33 - 5
14x = 28
x = 2

y = 4x - 11
= 4 . 2 - 11
= 8 - 11
= -3

Jadi, titik potongnya yaitu (2, -3)

3y = -2x - 5
3(4x - 11) = -2x - 5
12x - 33 = -2x - 5
12x + 2x = -5 + 33
14x = 28
x = 28 : 14
x = 2

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

Titik potong = (2 , -3)
