Kua tāruatia ki te papatopenga
4x=12+4y
Me tāpiri te 4y ki ngā taha e rua.
4x=4y+12
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{4y+12}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{4y+12}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=y+3
Whakawehe 12+4y ki te 4.
-4y=12-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{-4y}{-4}=\frac{12-4x}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{12-4x}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=x-3
Whakawehe 12-4x ki te -4.
