Kua tāruatia ki te papatopenga
3x+2\left(x-1\right)=12
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,6.
3x+2x-2=12
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te x-1.
5x-2=12
Pahekotia te 3x me 2x, ka 5x.
5x=12+2
Me tāpiri te 2 ki ngā taha e rua.
5x=14
Tāpirihia te 12 ki te 2, ka 14.
x=\frac{14}{5}
Whakawehea ngā taha e rua ki te 5.
