Kua tāruatia ki te papatopenga
2+2k=-28+7k
Whakareatia ngā taha e rua o te whārite ki te 7.
2+2k-7k=-28
Tangohia te 7k mai i ngā taha e rua.
2-5k=-28
Pahekotia te 2k me -7k, ka -5k.
-5k=-28-2
Tangohia te 2 mai i ngā taha e rua.
-5k=-30
Tangohia te 2 i te -28, ka -30.
k=\frac{-30}{-5}
Whakawehea ngā taha e rua ki te -5.
k=6
Whakawehea te -30 ki te -5, kia riro ko 6.
