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