Tohaina
Kua tāruatia ki te papatopenga
72x=288+x\left(-7\right)
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x.
72x-x\left(-7\right)=288
Tangohia te x\left(-7\right) mai i ngā taha e rua.
79x=288
Pahekotia te 72x me -x\left(-7\right), ka 79x.
x=\frac{288}{79}
Whakawehea ngā taha e rua ki te 79.
