48+33x=-12
Pahekotia te -3x me 36x, ka 33x.
33x=-12-48
Tangohia te 48 mai i ngā taha e rua.
33x=-60
Tangohia te 48 i te -12, ka -60.
x=\frac{-60}{33}
Whakawehea ngā taha e rua ki te 33.
x=-\frac{20}{11}
Whakahekea te hautanga \frac{-60}{33} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
