pers.1dan pers.2 di kali 6 dan kali 2 agar mudah di eliminasi
4x+6-3x-6=36⇒ 4x-3y=36
4x+2y=4 _
-5y=32
y=-32/5
x⇒2x+y=2 ⇒2x+(-32/5)=2
2x=8 2/5
x=4 1/5
m/n=x/y=21/5 per -32/5=21/32
maaf jika salah
(4x+6-3y+6)/6=6
4x-3y+12=36
4x-3y=24 (#)
2x+y=2 maka y=2-2x
Substitusi nilai ini ke (#)
4x-3(2-2x)=24
4x-6+6x=24
10x=30
X=3=m maka y=2-2•3=2-6=-4=n
Maka m/n= 3/-4
