2x-y=5=> -y=5-2x
y=-5+2x
PAKAI CARA SUBTITUSI:
6x-5y=5
6x-5(-5+2x)=5
6x+25-10x=5
-4x+25=5
-4x=5-25
-4x=-20
x=-20/-4
x=5
y=-5+2x
y=-5+2(5)
y=-5+10
y=5
a=x
b=y
Jadi a:c adalah 5/5=1
semoga membantu:))
2x-y=5 (x3) 6x-3y=15 - (di kurangi)
-2y=10
y=10/-2
y=-5
6x-5y=5
6x-5(-5+2x)=5
6x+25-10x=5
-4x+25=5
-4x=5-25
-4x=-20
x=-20/-4
x=5
a=x
y=-5+2x b=y
y=-5+2(5)
y=-5+10 a:b=5/5
y=5 =1
