15x+48=0
Pahekotia te x me 14x, ka 15x.
15x=-48
Tangohia te 48 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-48}{15}
Whakawehea ngā taha e rua ki te 15.
x=-\frac{16}{5}
Whakahekea te hautanga \frac{-48}{15} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 3.
