Kua tāruatia ki te papatopenga
2.2x=-1.15+4
Me tāpiri te 4 ki ngā taha e rua.
2.2x=2.85
Tāpirihia te -1.15 ki te 4, ka 2.85.
x=\frac{2.85}{2.2}
Whakawehea ngā taha e rua ki te 2.2.
x=\frac{285}{220}
Whakarohaina te \frac{2.85}{2.2} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{57}{44}
Whakahekea te hautanga \frac{285}{220} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 5.
