Tohaina
Kua tāruatia ki te papatopenga
2f-2-10=-2
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te f-1.
2f-12=-2
Tangohia te 10 i te -2, ka -12.
2f=-2+12
Me tāpiri te 12 ki ngā taha e rua.
2f=10
Tāpirihia te -2 ki te 12, ka 10.
f=\frac{10}{2}
Whakawehea ngā taha e rua ki te 2.
f=5
Whakawehea te 10 ki te 2, kia riro ko 5.
