Kua tāruatia ki te papatopenga
54\times \frac{5}{6}=2\left(y+2\right)-3
Me whakarea ngā taha e rua o te whārite ki te 18, arā, te tauraro pātahi he tino iti rawa te kitea o 6,9.
\frac{54\times 5}{6}=2\left(y+2\right)-3
Tuhia te 54\times \frac{5}{6} hei hautanga kotahi.
\frac{270}{6}=2\left(y+2\right)-3
Whakareatia te 54 ki te 5, ka 270.
45=2\left(y+2\right)-3
Whakawehea te 270 ki te 6, kia riro ko 45.
45=2y+4-3
Whakamahia te āhuatanga tohatoha hei whakarea te 2 ki te y+2.
45=2y+1
Tangohia te 3 i te 4, ka 1.
2y+1=45
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2y=45-1
Tangohia te 1 mai i ngā taha e rua.
2y=44
Tangohia te 1 i te 45, ka 44.
y=\frac{44}{2}
Whakawehea ngā taha e rua ki te 2.
y=22
Whakawehea te 44 ki te 2, kia riro ko 22.
