Kua tāruatia ki te papatopenga
\sqrt{2}x+120=48
Whakareatia te 5 ki te 24, ka 120.
\sqrt{2}x=48-120
Tangohia te 120 mai i ngā taha e rua.
\sqrt{2}x=-72
Tangohia te 120 i te 48, ka -72.
\frac{\sqrt{2}x}{\sqrt{2}}=-\frac{72}{\sqrt{2}}
Whakawehea ngā taha e rua ki te \sqrt{2}.
x=-\frac{72}{\sqrt{2}}
Mā te whakawehe ki te \sqrt{2} ka wetekia te whakareanga ki te \sqrt{2}.
x=-36\sqrt{2}
Whakawehe -72 ki te \sqrt{2}.
