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