Kua tāruatia ki te papatopenga
\frac{2}{3}x=14+6
Me tāpiri te 6 ki ngā taha e rua.
\frac{2}{3}x=20
Tāpirihia te 14 ki te 6, ka 20.
x=20\times \frac{3}{2}
Me whakarea ngā taha e rua ki te \frac{3}{2}, te tau utu o \frac{2}{3}.
x=\frac{20\times 3}{2}
Tuhia te 20\times \frac{3}{2} hei hautanga kotahi.
x=\frac{60}{2}
Whakareatia te 20 ki te 3, ka 60.
x=30
Whakawehea te 60 ki te 2, kia riro ko 30.
