himpunan penyelesaian dari spdlv 4x-2y=16 dan x-3y=9

4x-2y=16 | =>4x-2y=16
x-3y=9 |×4 =>4x-12y=36

=>4x-2y=16 - 4x-12y=36
10y=-20
y=2

4x-2y=16
4x-2(2)=16
4x-4=16
4x=16+4
4x=20
x=5

hp={5,2}

maaf kalau salah

4x -2y = 16 |×1
x-3y = 9 |×4

4x -2y = 16
4x -12y = 36
__________-
10y = -20
y = -20/10
y = -2

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

hp = {3,-2}
