Kua tāruatia ki te papatopenga
3\left(x-7\right)=4\times 6
Me whakarea ngā taha e rua o te whārite ki te 12, arā, te tauraro pātahi he tino iti rawa te kitea o 4,3.
3x-21=4\times 6
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te x-7.
3x-21=24
Whakareatia te 4 ki te 6, ka 24.
3x=24+21
Me tāpiri te 21 ki ngā taha e rua.
3x=45
Tāpirihia te 24 ki te 21, ka 45.
x=\frac{45}{3}
Whakawehea ngā taha e rua ki te 3.
x=15
Whakawehea te 45 ki te 3, kia riro ko 15.
