Kua tāruatia ki te papatopenga
11\left(x+3\right)=9\left(x+7\right)
Tē taea kia ōrite te tāupe x ki -7 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 11\left(x+7\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+7,11.
11x+33=9\left(x+7\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 11 ki te x+3.
11x+33=9x+63
Whakamahia te āhuatanga tohatoha hei whakarea te 9 ki te x+7.
11x+33-9x=63
Tangohia te 9x mai i ngā taha e rua.
2x+33=63
Pahekotia te 11x me -9x, ka 2x.
2x=63-33
Tangohia te 33 mai i ngā taha e rua.
2x=30
Tangohia te 33 i te 63, ka 30.
x=\frac{30}{2}
Whakawehea ngā taha e rua ki te 2.
x=15
Whakawehea te 30 ki te 2, kia riro ko 15.
