Kua tāruatia ki te papatopenga
20.4+3.2x=1.8
Whakareatia te 3 ki te 6.8, ka 20.4.
3.2x=1.8-20.4
Tangohia te 20.4 mai i ngā taha e rua.
3.2x=-18.6
Tangohia te 20.4 i te 1.8, ka -18.6.
x=\frac{-18.6}{3.2}
Whakawehea ngā taha e rua ki te 3.2.
x=\frac{-186}{32}
Whakarohaina te \frac{-18.6}{3.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-\frac{93}{16}
Whakahekea te hautanga \frac{-186}{32} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
