3y-30=2x-10
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te y-10.
2x-10=3y-30
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2x=3y-30+10
Me tāpiri te 10 ki ngā taha e rua.
2x=3y-20
Tāpirihia te -30 ki te 10, ka -20.
\frac{2x}{2}=\frac{3y-20}{2}
Whakawehea ngā taha e rua ki te 2.
x=\frac{3y-20}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
x=\frac{3y}{2}-10
Whakawehe 3y-20 ki te 2.
3y-30=2x-10
Whakamahia te āhuatanga tohatoha hei whakarea te 3 ki te y-10.
3y=2x-10+30
Me tāpiri te 30 ki ngā taha e rua.
3y=2x+20
Tāpirihia te -10 ki te 30, ka 20.
\frac{3y}{3}=\frac{2x+20}{3}
Whakawehea ngā taha e rua ki te 3.
y=\frac{2x+20}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
