4.7-0.2x=-3.5
Tāpirihia te -0.3 ki te 5, ka 4.7.
-0.2x=-3.5-4.7
Tangohia te 4.7 mai i ngā taha e rua.
-0.2x=-8.2
Tangohia te 4.7 i te -3.5, ka -8.2.
x=\frac{-8.2}{-0.2}
Whakawehea ngā taha e rua ki te -0.2.
x=\frac{-82}{-2}
Whakarohaina te \frac{-8.2}{-0.2} mā te whakarea i te taurunga me te tauraro ki te 10.
x=41
Whakawehea te -82 ki te -2, kia riro ko 41.
