20x+58=0
Pahekotia te 12x me 8x, ka 20x.
20x=-58
Tangohia te 58 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-58}{20}
Whakawehea ngā taha e rua ki te 20.
x=-\frac{29}{10}
Whakahekea te hautanga \frac{-58}{20} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te 2.
