Tohaina
Kua tāruatia ki te papatopenga
0.86y+2-y=-0.8
Tangohia te y mai i ngā taha e rua.
-0.14y+2=-0.8
Pahekotia te 0.86y me -y, ka -0.14y.
-0.14y=-0.8-2
Tangohia te 2 mai i ngā taha e rua.
-0.14y=-2.8
Tangohia te 2 i te -0.8, ka -2.8.
y=\frac{-2.8}{-0.14}
Whakawehea ngā taha e rua ki te -0.14.
y=\frac{-280}{-14}
Whakarohaina te \frac{-2.8}{-0.14} mā te whakarea i te taurunga me te tauraro ki te 100.
y=20
Whakawehea te -280 ki te -14, kia riro ko 20.
