-0.2x=4.4-1.6
Tangohia te 1.6 mai i ngā taha e rua.
-0.2x=2.8
Tangohia te 1.6 i te 4.4, ka 2.8.
x=\frac{2.8}{-0.2}
Whakawehea ngā taha e rua ki te -0.2.
x=\frac{28}{-2}
Whakarohaina te \frac{2.8}{-0.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=-14
Whakawehea te 28 ki te -2, kia riro ko -14.
