5x+2y=21x+y
Pahekotia te 20x me x, ka 21x.
5x+2y-21x=y
Tangohia te 21x mai i ngā taha e rua.
-16x+2y=y
Pahekotia te 5x me -21x, ka -16x.
-16x=y-2y
Tangohia te 2y mai i ngā taha e rua.
-16x=-y
Pahekotia te y me -2y, ka -y.
\frac{-16x}{-16}=-\frac{y}{-16}
Whakawehea ngā taha e rua ki te -16.
x=-\frac{y}{-16}
Mā te whakawehe ki te -16 ka wetekia te whakareanga ki te -16.
x=\frac{y}{16}
Whakawehe -y ki te -16.
5x+2y=21x+y
Pahekotia te 20x me x, ka 21x.
5x+2y-y=21x
Tangohia te y mai i ngā taha e rua.
5x+y=21x
Pahekotia te 2y me -y, ka y.
y=21x-5x
Tangohia te 5x mai i ngā taha e rua.
y=16x
Pahekotia te 21x me -5x, ka 16x.
