2.1x-6.45+4.3x=3.15
Me tāpiri te 4.3x ki ngā taha e rua.
6.4x-6.45=3.15
Pahekotia te 2.1x me 4.3x, ka 6.4x.
6.4x=3.15+6.45
Me tāpiri te 6.45 ki ngā taha e rua.
6.4x=9.6
Tāpirihia te 3.15 ki te 6.45, ka 9.6.
x=\frac{9.6}{6.4}
Whakawehea ngā taha e rua ki te 6.4.
x=\frac{96}{64}
Whakarohaina te \frac{9.6}{6.4} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{3}{2}
Whakahekea te hautanga \frac{96}{64} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 32.
