Kua tāruatia ki te papatopenga
\frac{5}{2}x=500-40
Tangohia te 40 mai i ngā taha e rua.
\frac{5}{2}x=460
Tangohia te 40 i te 500, ka 460.
x=460\times \frac{2}{5}
Me whakarea ngā taha e rua ki te \frac{2}{5}, te tau utu o \frac{5}{2}.
x=\frac{460\times 2}{5}
Tuhia te 460\times \frac{2}{5} hei hautanga kotahi.
x=\frac{920}{5}
Whakareatia te 460 ki te 2, ka 920.
x=184
Whakawehea te 920 ki te 5, kia riro ko 184.
