Kua tāruatia ki te papatopenga
8u-46=2u-10
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te u-5.
8u-46-2u=-10
Tangohia te 2u mai i ngā taha e rua.
6u-46=-10
Pahekotia te 8u me -2u, ka 6u.
6u=-10+46
Me tāpiri te 46 ki ngā taha e rua.
6u=36
Tāpirihia te -10 ki te 46, ka 36.
u=\frac{36}{6}
Whakawehea ngā taha e rua ki te 6.
u=6
Whakawehea te 36 ki te 6, kia riro ko 6.
