Graph
Tohaina
Kua tāruatia ki te papatopenga
x=-5+2y+1
Me tāpiri te 1 ki ngā taha e rua.
x=-4+2y
Tāpirihia te -5 ki te 1, ka -4.
-5+2y=-1+x
Whakawhitihia ngā taha kia puta ki te taha mauī ngā kīanga tau taurangi katoa.
2y=-1+x+5
Me tāpiri te 5 ki ngā taha e rua.
2y=4+x
Tāpirihia te -1 ki te 5, ka 4.
2y=x+4
He hanga arowhānui tō te whārite.
\frac{2y}{2}=\frac{x+4}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{x+4}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=\frac{x}{2}+2
Whakawehe 4+x ki te 2.
