4x-32x+2=0
Tātaihia te 2 mā te pū o 2, kia riro ko 4.
-28x+2=0
Pahekotia te 4x me -32x, ka -28x.
-28x=-2
Tangohia te 2 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-2}{-28}
Whakawehea ngā taha e rua ki te -28.
x=\frac{1}{14}
Whakahekea te hautanga \frac{-2}{-28} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -2.
