Kua tāruatia ki te papatopenga
-25\times 8=x-8y
Me whakarea ngā taha e rua ki te 8.
-200=x-8y
Whakareatia te -25 ki te 8, ka -200.
x-8y=-200
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
x=-200+8y
Me tāpiri te 8y ki ngā taha e rua.
-25\times 8=x-8y
Me whakarea ngā taha e rua ki te 8.
-200=x-8y
Whakareatia te -25 ki te 8, ka -200.
x-8y=-200
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-8y=-200-x
Tangohia te x mai i ngā taha e rua.
-8y=-x-200
He hanga arowhānui tō te whārite.
\frac{-8y}{-8}=\frac{-x-200}{-8}
Whakawehea ngā taha e rua ki te -8.
y=\frac{-x-200}{-8}
Mā te whakawehe ki te -8 ka wetekia te whakareanga ki te -8.
y=\frac{x}{8}+25
Whakawehe -200-x ki te -8.
