18+0.275x-x=0
Tangohia te x mai i ngā taha e rua.
18-0.725x=0
Pahekotia te 0.275x me -x, ka -0.725x.
-0.725x=-18
Tangohia te 18 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-18}{-0.725}
Whakawehea ngā taha e rua ki te -0.725.
x=\frac{-18000}{-725}
Whakarohaina te \frac{-18}{-0.725} mā te whakarea i te taurunga me te tauraro ki te 1000.
x=\frac{720}{29}
Whakahekea te hautanga \frac{-18000}{-725} ki ōna wāhi pāpaku rawa mā te tango me te whakakore i te -25.
