-4x+2y-8x=-6
Tangohia te 8x mai i ngā taha e rua.
-12x+2y=-6
Pahekotia te -4x me -8x, ka -12x.
-12x=-6-2y
Tangohia te 2y mai i ngā taha e rua.
-12x=-2y-6
He hanga arowhānui tō te whārite.
\frac{-12x}{-12}=\frac{-2y-6}{-12}
Whakawehea ngā taha e rua ki te -12.
x=\frac{-2y-6}{-12}
Mā te whakawehe ki te -12 ka wetekia te whakareanga ki te -12.
x=\frac{y}{6}+\frac{1}{2}
Whakawehe -6-2y ki te -12.
2y=8x-6+4x
Me tāpiri te 4x ki ngā taha e rua.
2y=12x-6
Pahekotia te 8x me 4x, ka 12x.
\frac{2y}{2}=\frac{12x-6}{2}
Whakawehea ngā taha e rua ki te 2.
y=\frac{12x-6}{2}
Mā te whakawehe ki te 2 ka wetekia te whakareanga ki te 2.
y=6x-3
Whakawehe 12x-6 ki te 2.
