Tohaina
Kua tāruatia ki te papatopenga
0=12+3m-15
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te m-5.
0=-3+3m
Tangohia te 15 i te 12, ka -3.
-3+3m=0
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3m=3
Me tāpiri te 3 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
m=\frac{3}{3}
Whakawehea ngā taha e rua ki te 3.
m=1
Whakawehea te 3 ki te 3, kia riro ko 1.
