Tohaina
Kua tāruatia ki te papatopenga
5p-15+2p=27
Me tāpiri te 2p ki ngā taha e rua.
7p-15=27
Pahekotia te 5p me 2p, ka 7p.
7p=27+15
Me tāpiri te 15 ki ngā taha e rua.
7p=42
Tāpirihia te 27 ki te 15, ka 42.
p=\frac{42}{7}
Whakawehea ngā taha e rua ki te 7.
p=6
Whakawehea te 42 ki te 7, kia riro ko 6.
