Kua tāruatia ki te papatopenga
2x-5=3\left(x+1\right)
Tē taea kia ōrite te tāupe x ki -1 nā te kore tautuhi i te whakawehenga mā te kore. Whakareatia ngā taha e rua o te whārite ki te x+1.
2x-5=3x+3
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x+1.
2x-5-3x=3
Tangohia te 3x mai i ngā taha e rua.
-x-5=3
Pahekotia te 2x me -3x, ka -x.
-x=3+5
Me tāpiri te 5 ki ngā taha e rua.
-x=8
Tāpirihia te 3 ki te 5, ka 8.
x=-8
Me whakarea ngā taha e rua ki te -1.
