Kua tāruatia ki te papatopenga
635\times 100=63x+65y
Me whakarea ngā taha e rua ki te 100.
63500=63x+65y
Whakareatia te 635 ki te 100, ka 63500.
63x+65y=63500
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
63x=63500-65y
Tangohia te 65y mai i ngā taha e rua.
\frac{63x}{63}=\frac{63500-65y}{63}
Whakawehea ngā taha e rua ki te 63.
x=\frac{63500-65y}{63}
Mā te whakawehe ki te 63 ka wetekia te whakareanga ki te 63.
635\times 100=63x+65y
Me whakarea ngā taha e rua ki te 100.
63500=63x+65y
Whakareatia te 635 ki te 100, ka 63500.
63x+65y=63500
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
65y=63500-63x
Tangohia te 63x mai i ngā taha e rua.
\frac{65y}{65}=\frac{63500-63x}{65}
Whakawehea ngā taha e rua ki te 65.
y=\frac{63500-63x}{65}
Mā te whakawehe ki te 65 ka wetekia te whakareanga ki te 65.
y=-\frac{63x}{65}+\frac{12700}{13}
Whakawehe 63500-63x ki te 65.
