Tohaina
Kua tāruatia ki te papatopenga
-11f=7-14f+5
Whakamahia te āhuatanga tohatoha hei whakarea te 7 ki te 1-2f.
-11f=12-14f
Tāpirihia te 7 ki te 5, ka 12.
-11f+14f=12
Me tāpiri te 14f ki ngā taha e rua.
3f=12
Pahekotia te -11f me 14f, ka 3f.
f=\frac{12}{3}
Whakawehea ngā taha e rua ki te 3.
f=4
Whakawehea te 12 ki te 3, kia riro ko 4.
