z=5
Tohaina
Kua tāruatia ki te papatopenga
2z-31+9z=24
Me tāpiri te 9z ki ngā taha e rua.
11z-31=24
Pahekotia te 2z me 9z, ka 11z.
11z=24+31
Me tāpiri te 31 ki ngā taha e rua.
11z=55
Tāpirihia te 24 ki te 31, ka 55.
z=\frac{55}{11}
Whakawehea ngā taha e rua ki te 11.
z=5
Whakawehea te 55 ki te 11, kia riro ko 5.
