10x+y-2x=11y
Tangohia te 2x mai i ngā taha e rua.
8x+y=11y
Pahekotia te 10x me -2x, ka 8x.
8x=11y-y
Tangohia te y mai i ngā taha e rua.
8x=10y
Pahekotia te 11y me -y, ka 10y.
\frac{8x}{8}=\frac{10y}{8}
Whakawehea ngā taha e rua ki te 8.
x=\frac{10y}{8}
Mā te whakawehe ki te 8 ka wetekia te whakareanga ki te 8.
x=\frac{5y}{4}
Whakawehe 10y ki te 8.
10x+y-11y=2x
Tangohia te 11y mai i ngā taha e rua.
10x-10y=2x
Pahekotia te y me -11y, ka -10y.
-10y=2x-10x
Tangohia te 10x mai i ngā taha e rua.
-10y=-8x
Pahekotia te 2x me -10x, ka -8x.
\frac{-10y}{-10}=-\frac{8x}{-10}
Whakawehea ngā taha e rua ki te -10.
y=-\frac{8x}{-10}
Mā te whakawehe ki te -10 ka wetekia te whakareanga ki te -10.
y=\frac{4x}{5}
Whakawehe -8x ki te -10.
