Kua tāruatia ki te papatopenga
7x=10\left(x-3\right)
Tē taea kia ōrite te tāupe x ki 0 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 10x, arā, te tauraro pātahi he tino iti rawa te kitea o 10,x.
7x=10x-30
Whakamahia te āhuatanga tohatoha hei whakarea te 10 ki te x-3.
7x-10x=-30
Tangohia te 10x mai i ngā taha e rua.
-3x=-30
Pahekotia te 7x me -10x, ka -3x.
x=\frac{-30}{-3}
Whakawehea ngā taha e rua ki te -3.
x=10
Whakawehea te -30 ki te -3, kia riro ko 10.
