Kua tāruatia ki te papatopenga
2+2x\times 25=150
Tātaihia te 5 mā te pū o 2, kia riro ko 25.
2+50x=150
Whakareatia te 2 ki te 25, ka 50.
50x=150-2
Tangohia te 2 mai i ngā taha e rua.
50x=148
Tangohia te 2 i te 150, ka 148.
x=\frac{148}{50}
Whakawehea ngā taha e rua ki te 50.
x=\frac{74}{25}
Whakahekea te hautanga \frac{148}{50} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
