Kua tāruatia ki te papatopenga
\sqrt{2}x-x=5
Tangohia te x mai i ngā taha e rua.
\left(\sqrt{2}-1\right)x=5
Pahekotia ngā kīanga tau katoa e whai ana i te x.
\frac{\left(\sqrt{2}-1\right)x}{\sqrt{2}-1}=\frac{5}{\sqrt{2}-1}
Whakawehea ngā taha e rua ki te \sqrt{2}-1.
x=\frac{5}{\sqrt{2}-1}
Mā te whakawehe ki te \sqrt{2}-1 ka wetekia te whakareanga ki te \sqrt{2}-1.
x=5\sqrt{2}+5
Whakawehe 5 ki te \sqrt{2}-1.
