Kua tāruatia ki te papatopenga
x-3=2\left(x-5\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 2x, arā, te tauraro pātahi he tino iti rawa te kitea o 2x,x.
x-3=2x-10
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-5.
x-3-2x=-10
Tangohia te 2x mai i ngā taha e rua.
-x-3=-10
Pahekotia te x me -2x, ka -x.
-x=-10+3
Me tāpiri te 3 ki ngā taha e rua.
-x=-7
Tāpirihia te -10 ki te 3, ka -7.
x=7
Me whakarea ngā taha e rua ki te -1.
Ngā Tauira
