Kua tāruatia ki te papatopenga
4x-12=\frac{2}{0.5}
Whakawehea ngā taha e rua ki te 0.5.
4x-12=\frac{20}{5}
Whakarohaina te \frac{2}{0.5} mā te whakarea i te taurunga me te tauraro ki te 10.
4x-12=4
Whakawehea te 20 ki te 5, kia riro ko 4.
4x=4+12
Me tāpiri te 12 ki ngā taha e rua.
4x=16
Tāpirihia te 4 ki te 12, ka 16.
x=\frac{16}{4}
Whakawehea ngā taha e rua ki te 4.
x=4
Whakawehea te 16 ki te 4, kia riro ko 4.
