Tohaina
Kua tāruatia ki te papatopenga
2.5x-2=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2.5x=y+2
Me tāpiri te 2 ki ngā taha e rua.
\frac{2.5x}{2.5}=\frac{y+2}{2.5}
Whakawehea ngā taha e rua o te whārite ki te 2.5, he ōrite ki te whakarea i ngā taha e rua ki te tau huripoki o te hautanga.
x=\frac{y+2}{2.5}
Mā te whakawehe ki te 2.5 ka wetekia te whakareanga ki te 2.5.
x=\frac{2y+4}{5}
Whakawehe y+2 ki te 2.5 mā te whakarea y+2 ki te tau huripoki o 2.5.
