Kua tāruatia ki te papatopenga
2x-8=\frac{16}{4}
Whakawehea ngā taha e rua ki te 4.
2x-8=4
Whakawehea te 16 ki te 4, kia riro ko 4.
2x=4+8
Me tāpiri te 8 ki ngā taha e rua.
2x=12
Tāpirihia te 4 ki te 8, ka 12.
x=\frac{12}{2}
Whakawehea ngā taha e rua ki te 2.
x=6
Whakawehea te 12 ki te 2, kia riro ko 6.
