Tohaina
Kua tāruatia ki te papatopenga
-8u+6u-24=-8
Whakamahia te āhuatanga tohatoha hei whakarea te 6 ki te u-4.
-2u-24=-8
Pahekotia te -8u me 6u, ka -2u.
-2u=-8+24
Me tāpiri te 24 ki ngā taha e rua.
-2u=16
Tāpirihia te -8 ki te 24, ka 16.
u=\frac{16}{-2}
Whakawehea ngā taha e rua ki te -2.
u=-8
Whakawehea te 16 ki te -2, kia riro ko -8.
