9.89-2.8x=4.9
Tāpirihia te 4.5 ki te 0.4, ka 4.9.
-2.8x=4.9-9.89
Tangohia te 9.89 mai i ngā taha e rua.
-2.8x=-4.99
Tangohia te 9.89 i te 4.9, ka -4.99.
x=\frac{-4.99}{-2.8}
Whakawehea ngā taha e rua ki te -2.8.
x=\frac{-499}{-280}
Whakarohaina te \frac{-4.99}{-2.8} mā te whakarea i te taurunga me te tauraro ki te 100.
x=\frac{499}{280}
Ka taea te hautanga \frac{-499}{-280} te whakamāmā ki te \frac{499}{280} mā te tango tahi i te tohu tōraro i te taurunga me te tauraro.
