Kua tāruatia ki te papatopenga
\frac{1}{2}y-2-\frac{1}{3}y=0
Tangohia te \frac{1}{3}y mai i ngā taha e rua.
\frac{1}{6}y-2=0
Pahekotia te \frac{1}{2}y me -\frac{1}{3}y, ka \frac{1}{6}y.
\frac{1}{6}y=2
Me tāpiri te 2 ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
y=2\times 6
Me whakarea ngā taha e rua ki te 6, te tau utu o \frac{1}{6}.
y=12
Whakareatia te 2 ki te 6, ka 12.
