Tohaina
Kua tāruatia ki te papatopenga
4a-3-\left(-a\right)=17
Hei kimi i te tauaro o 3-a, kimihia te tauaro o ia taurangi.
4a-3+a=17
Ko te tauaro o -a ko a.
5a-3=17
Pahekotia te 4a me a, ka 5a.
5a=17+3
Me tāpiri te 3 ki ngā taha e rua.
5a=20
Tāpirihia te 17 ki te 3, ka 20.
a=\frac{20}{5}
Whakawehea ngā taha e rua ki te 5.
a=4
Whakawehea te 20 ki te 5, kia riro ko 4.
