Kua tāruatia ki te papatopenga
A=5x+40
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+8.
5x+40=A
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5x=A-40
Tangohia te 40 mai i ngā taha e rua.
\frac{5x}{5}=\frac{A-40}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{A-40}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=\frac{A}{5}-8
Whakawehe A-40 ki te 5.
A=5x+40
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x+8.
