Tohaina
Kua tāruatia ki te papatopenga
200-x-0.25x=0
Tangohia te 0.25x mai i ngā taha e rua.
200-1.25x=0
Pahekotia te -x me -0.25x, ka -1.25x.
-1.25x=-200
Tangohia te 200 mai i ngā taha e rua. Ko te tau i tango i te kore ka hua ko tōna korenga.
x=\frac{-200}{-1.25}
Whakawehea ngā taha e rua ki te -1.25.
x=\frac{-20000}{-125}
Whakarohaina te \frac{-200}{-1.25} mā te whakarea i te taurunga me te tauraro ki te 100.
x=160
Whakawehea te -20000 ki te -125, kia riro ko 160.
