Whakaoti mō x
x = \frac{5}{4} = 1\frac{1}{4} = 1.25
Whakaoti mō y
y = -\frac{5}{4} = -1\frac{1}{4} = -1.25

Kua tāruatia ki te papatopenga
4x=5+4y
Me tāpiri te 4y ki ngā taha e rua.
4x=4y+5
He hanga arowhānui tō te whārite.
\frac{4x}{4}=\frac{4y+5}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{4y+5}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
x=y+\frac{5}{4}
Whakawehe 5+4y ki te 4.
-4y=5-4x
Tangohia te 4x mai i ngā taha e rua.
\frac{-4y}{-4}=\frac{5-4x}{-4}
Whakawehea ngā taha e rua ki te -4.
y=\frac{5-4x}{-4}
Mā te whakawehe ki te -4 ka wetekia te whakareanga ki te -4.
y=x-\frac{5}{4}
Whakawehe 5-4x ki te -4.
