Kua tāruatia ki te papatopenga
y-220=5x-300
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-60.
5x-300=y-220
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
5x=y-220+300
Me tāpiri te 300 ki ngā taha e rua.
5x=y+80
Tāpirihia te -220 ki te 300, ka 80.
\frac{5x}{5}=\frac{y+80}{5}
Whakawehea ngā taha e rua ki te 5.
x=\frac{y+80}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
x=\frac{y}{5}+16
Whakawehe y+80 ki te 5.
y-220=5x-300
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-60.
y=5x-300+220
Me tāpiri te 220 ki ngā taha e rua.
y=5x-80
Tāpirihia te -300 ki te 220, ka -80.
