Kua tāruatia ki te papatopenga
6x-2y=27
Whakareatia te 2 ki te 3, ka 6.
6x=27+2y
Me tāpiri te 2y ki ngā taha e rua.
6x=2y+27
He hanga arowhānui tō te whārite.
\frac{6x}{6}=\frac{2y+27}{6}
Whakawehea ngā taha e rua ki te 6.
x=\frac{2y+27}{6}
Mā te whakawehe ki te 6 ka wetekia te whakareanga ki te 6.
x=\frac{y}{3}+\frac{9}{2}
Whakawehe 27+2y ki te 6.
6x-2y=27
Whakareatia te 2 ki te 3, ka 6.
-2y=27-6x
Tangohia te 6x mai i ngā taha e rua.
\frac{-2y}{-2}=\frac{27-6x}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{27-6x}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=3x-\frac{27}{2}
Whakawehe 27-6x ki te -2.
