Kua tāruatia ki te papatopenga
24+2y=3x-5
Tāpirihia te -9 ki te 4, ka -5.
3x-5=24+2y
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
3x=24+2y+5
Me tāpiri te 5 ki ngā taha e rua.
3x=29+2y
Tāpirihia te 24 ki te 5, ka 29.
3x=2y+29
He hanga arowhānui tō te whārite.
\frac{3x}{3}=\frac{2y+29}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{2y+29}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
24+2y=3x-5
Tāpirihia te -9 ki te 4, ka -5.
2y=3x-5-24
Tangohia te 24 mai i ngā taha e rua.
2y=3x-29
Tangohia te 24 i te -5, ka -29.
\frac{2y}{2}=\frac{3x-29}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{3x-29}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
