3x - 2y = 16_+
5x + 3y = 14
jadi nilai 5x + 3y = 14
==========
cara lamanya dengan mencari nilai x dan y
3x - 2y = 16
kalikan 2
6x - 4y = 32
2x + 5y = -2
kalikan 3
6x + 15y = -6
eliminasi
6x - 4y = 32
6x + 15y = -6_-
-19y = 38
19y = -38
y = -38 / 19
y = -2
3x - 2y = 16
3x - 2(-2) = 16
3x + 4 = 16
3x = 16 - 4
3x = 12
x = 12 / 3
x = 4
5x + 3y = 5(4) + 3(-2)
= 20 - 6
= 14
