-0.04x+1.4=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
-0.04x=-1.4
Tangohia te 1.4 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-1.4}{-0.04}
Whakawehea ngā taha e rua ki te -0.04.
x=\frac{-140}{-4}
Whakarohaina te \frac{-1.4}{-0.04} mā te whakarea i te taurunga me te tauraro ki te 100.
x=35
Whakawehea te -140 ki te -4, kia riro ko 35.
