Kua tāruatia ki te papatopenga
2x=8+6y
Me tāpiri te 6y ki ngā taha e rua.
2x=6y+8
He hanga arowhānui tō te whārite.
\frac{2x}{2}=\frac{6y+8}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{6y+8}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=3y+4
Whakawehe 8+6y ki te 2.
-6y=8-2x
Tangohia te 2x mai i ngā taha e rua.
\frac{-6y}{-6}=\frac{8-2x}{-6}
Whakawehea ngā taha e rua ki te -6.
y=\frac{8-2x}{-6}
Mā te whakawehe ki te -6 ka wetekia te whakareanga ki te -6.
y=\frac{x-4}{3}
Whakawehe 8-2x ki te -6.
