Kua tāruatia ki te papatopenga
x\sqrt{2}=4+2y
Me tāpiri te 2y ki ngā taha e rua.
\sqrt{2}x=2y+4
He hanga arowhānui tō te whārite.
\frac{\sqrt{2}x}{\sqrt{2}}=\frac{2y+4}{\sqrt{2}}
Whakawehea ngā taha e rua ki te \sqrt{2}.
x=\frac{2y+4}{\sqrt{2}}
Mā te whakawehe ki te \sqrt{2} ka wetekia te whakareanga ki te \sqrt{2}.
x=\sqrt{2}\left(y+2\right)
Whakawehe 4+2y ki te \sqrt{2}.
-2y=4-x\sqrt{2}
Tangohia te x\sqrt{2} mai i ngā taha e rua.
-2y=-\sqrt{2}x+4
Whakaraupapatia anō ngā kīanga tau.
\frac{-2y}{-2}=\frac{-\sqrt{2}x+4}{-2}
Whakawehea ngā taha e rua ki te -2.
y=\frac{-\sqrt{2}x+4}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{\sqrt{2}x}{2}-2
Whakawehe -\sqrt{2}x+4 ki te -2.
