Kua tāruatia ki te papatopenga
4x+5=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
4x=-5
Tangohia te 5 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-5}{4}
Whakawehea ngā taha e rua ki te 4.
x=-\frac{5}{4}
Ka taea te hautanga \frac{-5}{4} te tuhi anō ko -\frac{5}{4} mā te tango i te tohu tōraro.
