50x=6400-64y
Tangohia te 64y mai i ngā taha e rua.
\frac{50x}{50}=\frac{6400-64y}{50}
Whakawehea ngā taha e rua ki te 50.
x=\frac{6400-64y}{50}
Mā te whakawehe ki te 50 ka wetekia te whakareanga ki te 50.
x=-\frac{32y}{25}+128

64y=6400-50x
Tangohia te 50x mai i ngā taha e rua.
\frac{64y}{64}=\frac{6400-50x}{64}
Whakawehea ngā taha e rua ki te 64.
y=\frac{6400-50x}{64}
Mā te whakawehe ki te 64 ka wetekia te whakareanga ki te 64.
y=-\frac{25x}{32}+100
