Kua tāruatia ki te papatopenga
4x+2y=3600\times 11000
Me whakarea ngā taha e rua ki te 11000.
4x+2y=39600000
Whakareatia te 3600 ki te 11000, ka 39600000.
4x=39600000-2y
Tangohia te 2y mai i ngā taha e rua.
\frac{4x}{4}=\frac{39600000-2y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{39600000-2y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=-\frac{y}{2}+9900000
Whakawehe 39600000-2y ki te 4.
4x+2y=3600\times 11000

4x+2y=39600000
Whakareatia te 3600 ki te 11000, ka 39600000.
2y=39600000-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{2y}{2}=\frac{39600000-4x}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{39600000-4x}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=19800000-2x
Whakawehe 39600000-4x ki te 2.
