Kua tāruatia ki te papatopenga
y=15x-825+55
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x-55.
y=15x-770
Tāpirihia te -825 ki te 55, ka -770.
15x-770=y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
15x=y+770
Me tāpiri te 770 ki ngā taha e rua.
\frac{15x}{15}=\frac{y+770}{15}
Whakawehea ngā taha e rua ki te 15.
x=\frac{y+770}{15}
Mā te whakawehe ki te 15 ka wetekia te whakareanga ki te 15.
x=\frac{y}{15}+\frac{154}{3}
Whakawehe y+770 ki te 15.
y=15x-825+55
Whakamahia te āhuatanga tohatoha hei whakarea te 15 ki te x-55.
y=15x-770
Tāpirihia te -825 ki te 55, ka -770.
