55x-33y-24x=48y
Tangohia te 24x mai i ngā taha e rua.
31x-33y=48y
Pahekotia te 55x me -24x, ka 31x.
31x=48y+33y
Me tāpiri te 33y ki ngā taha e rua.
31x=81y
Pahekotia te 48y me 33y, ka 81y.
\frac{31x}{31}=\frac{81y}{31}
Whakawehea ngā taha e rua ki te 31.
x=\frac{81y}{31}
Mā te whakawehe ki te 31 ka wetekia te whakareanga ki te 31.
55x-33y-48y=24x
Tangohia te 48y mai i ngā taha e rua.
55x-81y=24x
Pahekotia te -33y me -48y, ka -81y.
-81y=24x-55x
Tangohia te 55x mai i ngā taha e rua.
-81y=-31x
Pahekotia te 24x me -55x, ka -31x.
\frac{-81y}{-81}=-\frac{31x}{-81}
Whakawehea ngā taha e rua ki te -81.
y=-\frac{31x}{-81}
Mā te whakawehe ki te -81 ka wetekia te whakareanga ki te -81.
y=\frac{31x}{81}
