Tohaina
Kua tāruatia ki te papatopenga
11b-17-8b=28
Tangohia te 8b mai i ngā taha e rua.
3b-17=28
Pahekotia te 11b me -8b, ka 3b.
3b=28+17
Me tāpiri te 17 ki ngā taha e rua.
3b=45
Tāpirihia te 28 ki te 17, ka 45.
b=\frac{45}{3}
Whakawehea ngā taha e rua ki te 3.
b=15
Whakawehea te 45 ki te 3, kia riro ko 15.
