diketahui 4x-2y=2 dan 5x+4y=35 maka 3x+2y=

2(4x - 2y = 2)
1(5x + 4y = 35)

8x - 4y = 4
5x + 4y = 35
__________+
13x = 39
x = 3

4x - 2y = 2
4(3) - 2y = 2
12 - 2y = 2
-2y = -10
y = 5

3x + 2y
= 3(3) + 2(5)
= 9 + 10
= 19

[tex]4x - 2y = 2 \\ 5x + 4y = 35 \\ eliminasi \\ diklikn \: atas \: 2 \: bawah \: 1 \\ 8x - 4y = 4 \\ 5x + 4y = 35 \\ ditambh \\ 13x = 39 \\ x = 3 \\ substitusi \: nilai \: x \\ 4(3) - 2y = 2 \\ 12 - 2y = 2 \\ - 2y = - 10 \\ y = 5 \\ 3x + 2y = 3(3) + 2(5) = 9 + 10 = 19[/tex]
semoga bermanfaat maaf jika salah
