Kua tāruatia ki te papatopenga
6+6\left(x+3\right)\times \frac{1}{2}=2\left(x+3\right)
Tē taea kia ōrite te tāupe x ki -3 nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te 6\left(x+3\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+3,2,3.
6+3\left(x+3\right)=2\left(x+3\right)
Whakareatia te 6 ki te \frac{1}{2}, ka 3.
6+3x+9=2\left(x+3\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+3.
15+3x=2\left(x+3\right)
Tāpirihia te 6 ki te 9, ka 15.
15+3x=2x+6
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x+3.
15+3x-2x=6
Tangohia te 2x mai i ngā taha e rua.
15+x=6
Pahekotia te 3x me -2x, ka x.
x=6-15
Tangohia te 15 mai i ngā taha e rua.
x=-9
Tangohia te 15 i te 6, ka -9.
