Kua tāruatia ki te papatopenga
67=2\left(2x-3\right)-\left(x+1\right)
Me whakarea ngā taha e rua o te whārite ki te 4, arā, te tauraro pātahi he tino iti rawa te kitea o 4,2.
67=4x-6-\left(x+1\right)
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te 2x-3.
67=4x-6-x-1
Hei kimi i te tauaro o x+1, kimihia te tauaro o ia taurangi.
67=3x-6-1
Pahekotia te 4x me -x, ka 3x.
67=3x-7
Tangohia te 1 i te -6, ka -7.
3x-7=67
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=67+7
Me tāpiri te 7 ki ngā taha e rua.
3x=74
Tāpirihia te 67 ki te 7, ka 74.
x=\frac{74}{3}
Whakawehea ngā taha e rua ki te 3.
