bantu ya.. saya udah coba beberapa kali. tapi hasilnya gak dapat

3x/4 -½y = 4
=========== (X4)
3x - 2y = 16

x + 5y/2 = -1
=========== (X2)
2x + 5y = -2

3x-2y = 16 (X2) 6x -4y = 32
2x+5y = -2 (x3) 6x+15y = -6
======================= --
-19y = 38
y = -2

3x -2(-2) = 16
3x = 16-4
x = 12/3 = 4

5x +3y = 5(4) + 3(-2) = 20 -6 = 14

jawaban : B
