Kua tāruatia ki te papatopenga
20x=900\left(24-x\right)
Whakareatia te 3 ki te 300, ka 900.
20x=21600-900x
Whakamahia te āhuatanga tohatoha hei whakarea te 900 ki te 24-x.
20x+900x=21600
Me tāpiri te 900x ki ngā taha e rua.
920x=21600
Pahekotia te 20x me 900x, ka 920x.
x=\frac{21600}{920}
Whakawehea ngā taha e rua ki te 920.
x=\frac{540}{23}
Whakahekea te hautanga \frac{21600}{920} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 40.
