Kua tāruatia ki te papatopenga
16x+4y=68
Whakareatia ngā taha e rua o te whārite ki te 4.
16x=68-4y
Tangohia te 4y mai i ngā taha e rua.
\frac{16x}{16}=\frac{68-4y}{16}
Whakawehea ngā taha e rua ki te 16.
x=\frac{68-4y}{16}
Mā te whakawehe ki te 16 ka wetekia te whakareanga ki te 16.
x=\frac{17-y}{4}
Whakawehe 68-4y ki te 16.
16x+4y=68
Whakareatia ngā taha e rua o te whārite ki te 4.
4y=68-16x
Tangohia te 16x mai i ngā taha e rua.
\frac{4y}{4}=\frac{68-16x}{4}
Whakawehea ngā taha e rua ki te 4.
y=\frac{68-16x}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
y=17-4x
Whakawehe 68-16x ki te 4.
