\sqrt{2}+2x=7-5
Tangohia te 5 mai i ngā taha e rua.
\sqrt{2}+2x=2
Tangohia te 5 i te 7, ka 2.
2x=2-\sqrt{2}
Tangohia te \sqrt{2} mai i ngā taha e rua.
\frac{2x}{2}=\frac{2-\sqrt{2}}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{2-\sqrt{2}}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=-\frac{\sqrt{2}}{2}+1
Whakawehe 2-\sqrt{2} ki te 2.
