0.01x+3.1-2.03x=-2.96
Tangohia te 2.03x mai i ngā taha e rua.
-2.02x+3.1=-2.96
Pahekotia te 0.01x me -2.03x, ka -2.02x.
-2.02x=-2.96-3.1
Tangohia te 3.1 mai i ngā taha e rua.
-2.02x=-6.06
Tangohia te 3.1 i te -2.96, ka -6.06.
x=\frac{-6.06}{-2.02}
Whakawehea ngā taha e rua ki te -2.02.
x=\frac{-606}{-202}
Whakarohaina te \frac{-6.06}{-2.02} mā te whakarea i te taurunga me te tauraro ki te 100.
x=3
Whakawehea te -606 ki te -202, kia riro ko 3.
