-4x-3y+8y=-8x+11
Pahekotia te 6x me -10x, ka -4x.
-4x+5y=-8x+11
Pahekotia te -3y me 8y, ka 5y.
-4x+5y+8x=11
Me tāpiri te 8x ki ngā taha e rua.
4x+5y=11
Pahekotia te -4x me 8x, ka 4x.
4x=11-5y
Tangohia te 5y mai i ngā taha e rua.
\frac{4x}{4}=\frac{11-5y}{4}
Whakawehea ngā taha e rua ki te 4.
x=\frac{11-5y}{4}
Mā te whakawehe ki te 4 ka wetekia te whakareanga ki te 4.
-4x-3y+8y=-8x+11
Pahekotia te 6x me -10x, ka -4x.
-4x+5y=-8x+11
Pahekotia te -3y me 8y, ka 5y.
5y=-8x+11+4x
Me tāpiri te 4x ki ngā taha e rua.
5y=-4x+11
Pahekotia te -8x me 4x, ka -4x.
5y=11-4x
He hanga arowhānui tō te whārite.
\frac{5y}{5}=\frac{11-4x}{5}
Whakawehea ngā taha e rua ki te 5.
y=\frac{11-4x}{5}
Mā te whakawehe ki te 5 ka wetekia te whakareanga ki te 5.
