Kua tāruatia ki te papatopenga
10-x=\frac{1}{10}\times 30
Me whakarea ngā taha e rua ki te 30.
10-x=\frac{30}{10}
Whakareatia te \frac{1}{10} ki te 30, ka \frac{30}{10}.
10-x=3
Whakawehea te 30 ki te 10, kia riro ko 3.
-x=3-10
Tangohia te 10 mai i ngā taha e rua.
-x=-7
Tangohia te 10 i te 3, ka -7.
x=7
Me whakarea ngā taha e rua ki te -1.
