Kua tāruatia ki te papatopenga
\sqrt{2}x+12=48
Whakareatia te 5 ki te 2.4, ka 12.
\sqrt{2}x=48-12
Tangohia te 12 mai i ngā taha e rua.
\sqrt{2}x=36
Tangohia te 12 i te 48, ka 36.
\frac{\sqrt{2}x}{\sqrt{2}}=\frac{36}{\sqrt{2}}
Whakawehea ngā taha e rua ki te \sqrt{2}.
x=\frac{36}{\sqrt{2}}
Mā te whakawehe ki te \sqrt{2} ka wetekia te whakareanga ki te \sqrt{2}.
x=18\sqrt{2}
Whakawehe 36 ki te \sqrt{2}.
