bolpoin —> y
4x + 2y = 34000 x 3
3x + 1y = 23000 x 4
————————— -
agar bisa di eliminasi, kalikan dengan kpk untuk di x atau y
12x + 6y = 102.000
12x + 4y = 92.000
—————————— -
2y = 10.000
y = 5.000
substitusi nilai x
4x + 2 ( 5.000) = 34.000
4x + 10.000 = 34.000
4x = 34.000 - 10.000
4x = 24.000
x = 6.000
5x + 7y = .....
5(6000) + 7(5000) =
30.000 + 35.000 = 65.000
5x + 7y = 65.000
semoga membantu :)
