Kua tāruatia ki te papatopenga
-3x=-2.3+2
Me tāpiri te 2 ki ngā taha e rua.
-3x=-0.3
Tāpirihia te -2.3 ki te 2, ka -0.3.
x=\frac{-0.3}{-3}
Whakawehea ngā taha e rua ki te -3.
x=\frac{-3}{-30}
Whakarohaina te \frac{-0.3}{-3} mā te whakarea i te taurunga me te tauraro ki te 10.
x=\frac{1}{10}
Whakahekea te hautanga \frac{-3}{-30} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -3.
