5x-5y+3y=2x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-y.
5x-2y=2x
Pahekotia te -5y me 3y, ka -2y.
5x-2y-2x=0
Tangohia te 2x mai i ngā taha e rua.
3x-2y=0
Pahekotia te 5x me -2x, ka 3x.
3x=2y
Me tāpiri te 2y ki ngā taha e rua. Ko te tau i tāpiria he kore ka hua koia tonu.
\frac{3x}{3}=\frac{2y}{3}
Whakawehea ngā taha e rua ki te 3.
x=\frac{2y}{3}
Mā te whakawehe ki te 3 ka wetekia te whakareanga ki te 3.
5x-5y+3y=2x
Whakamahia te āhuatanga tohatoha hei whakarea te 5 ki te x-y.
5x-2y=2x
Pahekotia te -5y me 3y, ka -2y.
-2y=2x-5x
Tangohia te 5x mai i ngā taha e rua.
-2y=-3x
Pahekotia te 2x me -5x, ka -3x.
\frac{-2y}{-2}=-\frac{3x}{-2}
Whakawehea ngā taha e rua ki te -2.
y=-\frac{3x}{-2}
Mā te whakawehe ki te -2 ka wetekia te whakareanga ki te -2.
y=\frac{3x}{2}
Whakawehe -3x ki te -2.
