Kua tāruatia ki te papatopenga
x+2a=3\left(x-2\right)
Whakareatia ngā taha e rua o te whārite ki te x-2.
x+2a=3x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-2.
2a=3x-6-x
Tangohia te x mai i ngā taha e rua.
2a=2x-6
Pahekotia te 3x me -x, ka 2x.
\frac{2a}{2}=\frac{2x-6}{2}
Whakawehea ngā taha e rua ki te 2.
a=\frac{2x-6}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
a=x-3
Whakawehe -6+2x ki te 2.
x+2a=3\left(x-2\right)
Tē taea kia ōrite te tāupe x ki 2 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x-2.
x+2a=3x-6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-2.
x+2a-3x=-6
Tangohia te 3x mai i ngā taha e rua.
-2x+2a=-6
Pahekotia te x me -3x, ka -2x.
-2x=-6-2a
Tangohia te 2a mai i ngā taha e rua.
-2x=-2a-6
He hanga arowhānui tō te whārite.
\frac{-2x}{-2}=\frac{-2a-6}{-2}
Whakawehea ngā taha e rua ki te -2.
x=\frac{-2a-6}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
x=a+3
Whakawehe -6-2a ki te -2.
x=a+3\text{, }x\neq 2
Tē taea kia ōrite te tāupe x ki 2.
