dengan menggunakan metode substitusi selesaikanlah spldv berikut!a.5x+2y=1/2 dan -3x+2y=1/2

5x+2y=1/2
-3x+2y=1/2

2y = 1/2 - 5x

-3x+2y=1/2
-3x+(1/2 - 5x)=1/2
-8x + 1/2 = 1/2
-8x = 1/2-1/2
-8x = 0
x = 0

5x+2y=1/2

-3x+2y=1/2 (bagi -3)
x-2/3y=-1/6
x = 2/3y - 1/6

5(2/3y - 1/6) + 2y = 1/2
10/3y - 5/6 + 2y = 1/2
10/3y - 5/6 + 6/3y = 1/2
16/3y - 5/6 = 1/2
16/3y = 1/2 + 5/6 (kali 3/16)
y = 3/32 + 15/96
y = 9/96 + 15/96
y = 24/96
y = 1/4
