Tohaina
Kua tāruatia ki te papatopenga
1+2b-4b=9
Tangohia te 4b mai i ngā taha e rua.
1-2b=9
Pahekotia te 2b me -4b, ka -2b.
-2b=9-1
Tangohia te 1 mai i ngā taha e rua.
-2b=8
Tangohia te 1 i te 9, ka 8.
b=\frac{8}{-2}
Whakawehea ngā taha e rua ki te -2.
b=-4
Whakawehea te 8 ki te -2, kia riro ko -4.
