Kua tāruatia ki te papatopenga
\left(2x-1\right)\times 3=\left(x+2\right)\times 5
Tē taea kia ōrite te tāupe x ki tētahi o ngā uara -2,\frac{1}{2} nā te kore tautuhi i te whakawehenga mā te kore. Me whakarea ngā taha e rua o te whārite ki te \left(2x-1\right)\left(x+2\right), arā, te tauraro pātahi he tino iti rawa te kitea o x+2,2x-1.
6x-3=\left(x+2\right)\times 5
Whakamahia te āhuatanga tohatoha hei whakarea te 2x-1 ki te 3.
6x-3=5x+10
Whakamahia te āhuatanga tohatoha hei whakarea te x+2 ki te 5.
6x-3-5x=10
Tangohia te 5x mai i ngā taha e rua.
x-3=10
Pahekotia te 6x me -5x, ka x.
x=10+3
Me tāpiri te 3 ki ngā taha e rua.
x=13
Tāpirihia te 10 ki te 3, ka 13.
