6u+16=-4u+36
Whakamahia te āhuatanga tohatoha hei whakarea te -4 ki te u-9.
6u+16+4u=36
Me tāpiri te 4u ki ngā taha e rua.
10u+16=36
Pahekotia te 6u me 4u, ka 10u.
10u=36-16
Tangohia te 16 mai i ngā taha e rua.
10u=20
Tangohia te 16 i te 36, ka 20.
u=\frac{20}{10}
Whakawehea ngā taha e rua ki te 10.
u=2
Whakawehea te 20 ki te 10, kia riro ko 2.
