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

(1) y = 4x - 11
= 4x - y = 11

(2) 3y = -2x - 5
= 2x + 3y = -5
= 4x + 6y = -10

(2) - (1)

4x + 6y = -10
4x - y = 11
__________ (-)

7y = - 21
y = -3

(1) 4x - y = 11
= 4x - (-3) = 11
= 4x + 3 = 11
= 4x = 8
= x = 2

jadi titiknya adalah (2,-3)
