Tohaina
Kua tāruatia ki te papatopenga
2.5x=-500
Tangohia te 500 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-500}{2.5}
Whakawehea ngā taha e rua ki te 2.5.
x=\frac{-5000}{25}
Whakarohaina te \frac{-500}{2.5} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-200
Whakawehea te -5000 ki te 25, kia riro ko -200.
