x+1.5x=\frac{144}{2}
Whakawehea ngā taha e rua ki te 2.
x+1.5x=72
Whakawehea te 144 ki te 2, kia riro ko 72.
2.5x=72
Pahekotia te x me 1.5x, ka 2.5x.
x=\frac{72}{2.5}
Whakawehea ngā taha e rua ki te 2.5.
x=\frac{720}{25}
Whakarohaina te \frac{72}{2.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{144}{5}
Whakahekea te hautanga \frac{720}{25} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
