Kua tāruatia ki te papatopenga
3\times 5x=12x+2\left(x-2\right)
Me whakarea ngā taha e rua o te whārite ki te 6, arā, te tauraro pātahi he tino iti rawa te kitea o 2,3.
15x=12x+2\left(x-2\right)
Whakareatia te 3 ki te 5, ka 15.
15x=12x+2x-4
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-2.
15x=14x-4
Pahekotia te 12x me 2x, ka 14x.
15x-14x=-4
Tangohia te 14x mai i ngā taha e rua.
x=-4
Pahekotia te 15x me -14x, ka x.
