Kua tāruatia ki te papatopenga
3\times 6=2\left(m+5\right)
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.
18=2\left(m+5\right)
Whakareatia te 3 ki te 6, ka 18.
18=2m+10
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te m+5.
2m+10=18
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2m=18-10
Tangohia te 10 mai i ngā taha e rua.
2m=8
Tangohia te 10 i te 18, ka 8.
m=\frac{8}{2}
Whakawehea ngā taha e rua ki te 2.
m=4
Whakawehea te 8 ki te 2, kia riro ko 4.
