Tohaina
Kua tāruatia ki te papatopenga
a=4\left(a-12\right)
Tē taea kia ōrite te tāupe a ki 12 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te 2\left(a-12\right).
a=4a-48
Whakamahia te āhuatanga tohatoha hei whakarea te 4 ki te a-12.
a-4a=-48
Tangohia te 4a mai i ngā taha e rua.
-3a=-48
Pahekotia te a me -4a, ka -3a.
a=\frac{-48}{-3}
Whakawehea ngā taha e rua ki te -3.
a=16
Whakawehea te -48 ki te -3, kia riro ko 16.
